     BACKGROUND 
     Typically, digital photo frames display digital photos that are uploaded by a user via a memory card, Universal Serial Bus (USB) connection, or other method. However, one drawback to this approach is that it requires the user to have basic technological expertise in order to upload the digital photos to the digital photo frame. Because this approach requires a certain level of comfort with technology, some users may be dissuaded from utilizing digital photo frames. Accordingly, the need exists for digital photo frames that overcome the above limitations, in addition to providing other benefits.

     DETAILED DESCRIPTION 
     A digital display device for displaying content associated with multiple sets of sources of content is described herein. The digital display device includes a display configured to provide at least a first display region and a second display region. The digital display device further includes a communication component configured to transmit and receive signals to and from a telecommunications network and a storage component configured to store a mapping of sources of content to the first and second display regions. The digital display device also includes a routing component that automatically routes content associated with the first and second sets of sources for display on at least one of the first and second display regions. The first and second display regions display the content substantially simultaneously. 
     In some embodiments, the digital display device allows a user to engage in real-time communications with a source of content. The real time communication may be created with the source of content by selecting the display region that is displaying content that corresponds to the source of content. The digital display device establishes a real-time communication session with the corresponding source of content over the telecommunications network. 
     In some embodiments, the digital display device includes two or more displays that are coupled at angles to each other. For example, the digital display device may include three displays that are coupled to each other and may be arranged to form the shape of a triangle. As another example, the digital display device may include four displays that are coupled to each other and may be arranged to form the shape of a square. Each display is configured to provide one or more display regions in which content is displayed. The display regions may also be merged with one another to form a merged display region in which content is displayed. In some embodiments, the digital display device has the form of a cube with six faces. All or substantially all of the six faces may include a display having one or more display regions in which content is displayed. Two or more display regions may be merged with one-another to form a merged display region in which content is displayed. The displays may be touch-sensitive. Display regions may be merged by, for example, receiving a first touch from a user of a first touch-sensitive display region and a second touch of a second touch-sensitive display region. 
     The following description provides specific details for a thorough understanding of, and enabling description for, various embodiments of the technology. One skilled in the art will understand that the technology may be practiced without many of these details. In some instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments of the technology. It is intended that the terminology used in the description presented below be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain embodiments of the technology. Although certain terms may be emphasized below, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this Detailed Description section. 
       FIG. 1  is an isometric view of a digital display device  100  having multiple display regions that may be associated with sources of content. The digital display device  100  is supported by a stand  110  and includes a frame  105  and an antenna  115  attached to the frame  105 . In some embodiments, the antenna  115  is embodied within the frame  105  such that it is not apparent to an observer, or the frame  105  is configured to act as an antenna. In some embodiments, in addition to or instead of the stand  110 , the digital display device  100  includes a hanger configured to enable the digital display device  100  to be attached to a surface (e.g., a wall). The antenna  115  enables a wireless connection to a telecommunications network. In some embodiments, in addition to or in place of the antenna  115 , the digital display device  100  includes components (not shown in  FIG. 1 ) that enable a wired connection to a telecommunications network (e.g., an RJ-11 port, an Ethernet port, a cable modem port, or other wired port). The digital display device  100  also includes five display regions  120  (shown individually as display regions  120   a - e ). The digital display device  100  can include fewer than (e.g., one display region) or more than (e.g., six display regions) the depicted five display regions  120 . The digital display device  100  can also have the display regions  120  arranged in configurations other than the configuration illustrated in  FIG. 1 . For example, the display regions can all have portrait orientations or can all have landscape orientations, or some combination of portrait and landscape orientations. As another example, the display regions may be positioned adjacent to one another in a linear fashion. The display regions  120  can also have varying sizes and shapes (e.g., circular, elliptical, square, rectangular, polygonal, etc.). Each display region may be constructed using an individual display panel, such as a liquid crystal display (LCD), an Organic Light-Emitting Diode (OLED) display, a Liquid Crystal On Silicon (LCOS) display, etc. Alternatively, each display region may be a mapped region of a single, larger display panel. 
     The digital display device  100  also includes communication components and/or circuits (not shown in  FIG. 1 ) that enable the digital display device  100  to communicate by transmitting and receiving wireless signals using licensed, semi-licensed or unlicensed spectrum over a telecommunications network. Telecommunications networks include third-party telecommunications networks such as a Global System for Mobile (GSM) mobile telecommunications network, a code/time division multiple access (CDMA/TDMA) mobile telecommunications network, a 3rd Generation (3G) mobile telecommunications network (e.g. General Packet Radio Service (GPRS/EGPRS), Enhanced Data rates for GSM Evolution (EDGE), or Universal Mobile Telecommunications System (UMTS)), or other telecommunications network. For example, if the digital display device  100  is configured to communicate over a GSM mobile telecommunications network, the digital display device  100  may include a Subscriber Identity Module (SIM) card that stores an International Mobile Subscriber Identity (IMSI) number that can be used to identify the digital display device  100  on the GSM mobile telecommunications network. If the digital display device  100  is configured to communicate over another telecommunications network, the digital display device  100  may include other components that enable it to be identified on the other telecommunications network. Telecommunications networks also include local or home-based telecommunications networks, such as telecommunications networks using Generic Access Network (GAN) or Unlicensed/Universal Mobile Access (UMA) standards and protocols. In some embodiments, the digital display device  100  includes components that enable it to connect to a telecommunications network using the aforementioned GAN or UMA standards and protocols. For example, the digital display device  100  may include components that support Internet Protocol (IP)-based communication over a Wireless Local Area Network (WLAN) and components that enable communication with the telecommunications network over the IP-based WLAN. 
     Because the digital display device  100  is configured to communicate with a telecommunications network, the digital display device  100  incorporates an identifier that identifies it to the telecommunications network. Example identifiers include a telephone number, an IMSI, an e-mail address, an IP address, a Media Access Control (MAC) address, or other identifier. Because the digital display device  100  has an identifier assigned to it, the digital display device  100  can receive content that is sent to the identifier. As will be described in further detail with reference to e.g.,  FIGS. 5-6B , associations are created between each of the display regions  120  of the digital display device  100  and sources of content, either on a permanent basis or on a temporary basis. For example, display regions may be associated with sources used or operated by family members (e.g., children, grandchildren, etc.), friends, or colleagues. As another example, a display region may be associated with sources used or operated by a family or other group (e.g., a soccer team, a book club, etc.). As another example, the display regions may be temporarily mapped to respective sources, thereby enabling content from the sources to be displayed in alternating display regions. In some embodiments, the sources are used or operated by subscribers of the same telecommunications network to which the digital display device  100  is connected (e.g., the subscriber owns or utilizes a source device that connects to the same telecommunications network). The sources can send content (e.g., still photos or images, video clips, text messages, interactive video games, metadata associated with any of the foregoing or other types of content) to the identifier assigned to the digital display device  100 . The content is transmitted over the telecommunications network to a transceiving site (such as a base station or wireless router) serving the digital display device  100 . The digital display device  100  may store the content in a storage medium (not shown in  FIG. 1 ) such as a hard disk, flash memory, memory card, etc., located in the digital display device, in an external device accessible via a WLAN, a network location or at a server location accessible via the Internet. Upon receiving the indicated content, the digital display device  100  automatically displays the content in the display region  120  that is permanently or temporarily associated with the source that sent it. The digital display device  100  displays the content in the different display regions  120  substantially simultaneously. In some embodiments, each time that content is received by the digital display device  100 , the digital display device automatically displays the new content. In this way, the content displayed in the display regions  120  may be constantly refreshed. In some embodiments, the digital display device stores received content and successively displays the content on the display regions  120  (e.g., displays the stored content in slideshow fashion). 
     It will be appreciated that one advantage of the digital display device  100  is that it enables a user to enjoy new content associated with one or more sources without having to initiate the uploading of the new content. The digital display device  100  can therefore be successfully utilized by users with little or no technical expertise. Another advantage is that the user may enjoy content from a large number of sources at one time with a glance, in contrast to prior displays that require a user to wait while images are sequentially presented to the user. 
       FIG. 2  illustrates a flow of content from various sources to the digital display device  100 . Illustrated sources of content (i.e., content providers) include a mobile phone  215 , a digital camera  220 , another digital display device  225 , a digital video camera  230 , and a personal computer  235 . Other types of sources may include websites  240  and online content repositories  245 . The illustrated sources transmit content over a telecommunications network  200 , which transmits the content via a wireless signal  210  to the digital display device  100 . If a source is capable of sending content directly to the telecommunications network  200  (e.g., in the case of the source mobile phone  215 ), the content can be sent via a wireless connection  205   a  or wired connection  205   b . Alternatively, if the source is utilizing a device that is capable of sending content indirectly to the telecommunications network  200  (e.g., a device that connects indirectly to the telecommunications network via a network such as the Internet), the content may be sent over a wired (or wireless, or partially wired, partially wireless) connection to the telecommunications network  200 . For example, source personal computer  235  may connect to a website hosted by a computer that is part of the telecommunications network  200  and upload content to the website. The hosting computer can then provide the content or arrange to provide the content to the digital display device  100 . As another example, source digital camera  220  may wirelessly connect to a wireless network, via which content can be transmitted to the telecommunications network  200 . In some embodiments, the digital display device  100  can transmit and/or receive content using methods described in PCT/US08/54793 (entitled DATA EXCHANGE INITIATED BY TAPPING DEVICES), the entirety of which is hereby incorporated by reference. Those of skill in the art will understand that a source may be any of a variety of devices or applications that connect in a variety of ways to the telecommunications network  200 , and that content from those sources can be ultimately conveyed to the digital display device  100 . 
       FIG. 3  is an isometric view of a digital display device  300  configured in accordance with another embodiment of the invention. In addition to the illustrated components already discussed with reference to  FIG. 1 , the digital display device  300  includes audio output components  330  (shown individually as audio output components  330   a  and  330   b ). The audio output components are left and right stereo speakers that are configured to produce sound. The digital display device  300  also includes an audio input component  340  (e.g., a microphone) that is configured to receive sound. The digital display device  300  also includes touchscreen or touch-sensitive display regions  320  (shown individually as display regions  320   a - e ). The touch-sensitive display regions  320 , when activated or actuated by a user (e.g., by touch), are configured to cause the digital display device  300  to initiate a real-time communication session with the source associated with the content that is displayed on the touch-sensitive display region  320  at the time the touch-sensitive display region  320  is touched. For example, if an image of an individual who uses or operates a source (e.g., a digital photograph of the individual) is displayed in a particular display region  320 , the user can touch the particular display region  320  to cause the digital display device  300  to initiate a real-time communication session (such as a voice call, a video call, an e-mail, a text message, an instant messaging session or other communication) with that individual. For example, upon successfully reaching the individual after initiating a voice call, the user can speak into the audio input component  340  and hear the individual via sound generated by the audio output components  330 . The user can adjust the volume of the sound generated by the audio output components  330  by utilizing up and down buttons  335  or via the touchscreen. When the user desires to end the call, the user can again activate or actuate the touch-sensitive display region to cause the digital display device  300  to end the initiated voice communication. In some embodiments, a display region is associated with a source or sources used or operated by multiple individuals. For example, a display region may be associated with a source used or operated by two individuals. The user can touch the display region associated with the source to initiate real-time communications with the individuals (e.g., three-way calling; a chat room session, an instant messaging session). 
     In some embodiments, while a user is engaged in a real-time communication with a first individual, the user can initiate a second real-time communication session with a second individual who uses or operates a second source, and conference the two individuals together into a group real-time communication session. For example, a user already engaged in a voice communication with a first individual can initiate a second voice communication by activating or actuating a second touch-sensitive display region at the time the second touch-sensitive display region is displaying content associated with the second source. When the second voice communication with the second individual is successfully initiated, the user can conference in the two individuals by again activating or actuating the first touch-sensitive display region associated with the first source. Alternatively, if the second voice communication is not successfully initiated, the user can return to the first voice communication by activating or actuating the second touch-sensitive display region, thus causing it to end and returning the user to the first voice communication. Additional participants to the conference call can be similarly added. Other types of group real time communications can similarly be initiated in this fashion (e.g., a video conferencing session, an instant messaging session, a text messaging session, a chat room session, etc.). 
     The digital display device  300  also includes a camera  325  that is configured to capture still or moving images for transmittal to the telecommunications network and ultimately to a remote recipient, and a button (not shown in  FIG. 3 ) configured to activate the camera  325 . For example, a user can position himself or herself in front of the camera  325  and activate the camera  325  (e.g., by pressing the button, utilizing a remote or otherwise successfully triggering the digital display device&#39;s functionality) to capture a still or moving image of himself or herself. The user can then touch a touch-screen display region  320  to send the captured image to the individual using or operating the source associated with the touch-screen display region  320 . In some embodiments, the user can activate the camera  325  before or during an initiated real-time communication session and cause the digital display device  300  to transmit one or more still or moving images over the telecommunications network to a remote recipient. A user of the digital display device  300  can thus provide content to another user, such as another user of another digital display device. 
       FIG. 4  is a schematic view of components of the digital display device  300  having multiple display regions. The digital display device  300  includes various components that enable it to provide the functionality described herein as well as additional functionality. These components include an audio input component  405  (e.g., microphone) and an audio output component  410  (e.g., speakers). A user input component  430  (e.g., buttons, alpha-numerical keyboard, etc.) enables the user to interact with the digital display device (e.g., adjust speaker volume, access stored content, adjust configuration settings, etc.). A camera component  445  (e.g., digital camera) captures images (e.g., still or moving images). A storage medium component  435  (e.g., hard drive, flash memory, memory card, etc.) stores content and other data (e.g., processing instructions, configuration settings, etc.). A processor  450  executes processing instructions. The digital display device  300  also may include a SIM card interface  420 , which enables the digital display device  300  to receive a SIM card for purposes of accessing a GSM/GPRS/EDGE/UMTS telecommunications network, and an antenna  440  for transmitting and receiving wireless signals. The digital display device  300  also includes a power source  455  (e.g., batteries, AC/DC converter, etc.), a communication component  425 , which may include a GSM/CPRS/EDGE/UMTS component  425   a , a Bluetooth component  425   b , a Wi-Fi component  425   c  and/or a wired component  425   d  (e.g., RJ-11 port, Ethernet port, etc.). The Bluetooth component  425   b  and/or the Wi-Fi component  425   c  enable the digital display device  300  to transmit and receive wireless signals in the 2.4 GHz Industrial Scientific Medical (ISM) band. Other wireless protocols (e.g., Mobile Broadband Wireless Access (MBWA), Ultra Wideband (UWB), ZigBee and other protocols) may also be supported. The digital display device  300  also includes an infrared component  465  that enables communication over an infrared spectrum (e.g., for communicating with a remote control that operates the digital display device  300 ). The digital display device  300  also includes a display component  460 . The display component  460  may comprise one or several touchscreen liquid crystal displays  460  (shown individually as touchscreen displays  460   a - n ), each of which is associated with a display region. Alternatively, the digital display device may include a single touchscreen liquid crystal display that is mapped via software to provide the various display regions. The displays  460  display content associated with the display regions and are touch-activated to provide varied functionality. In addition to displaying content, the touchscreen displays  460  can display user interfaces (e.g. alphanumerical keyboard, buttons for selecting options, menus, etc.) that enable users to interact with the digital display device  300 , either by using the touchscreen displays or by a remote. The digital display device also includes a routing component  480  that automatically routes received content to the appropriate display  460 . The digital display device  300  also includes a real-time communication component  485  (e.g., hardware and/or software for audio and/or video communication, hardware and/or software for text messaging, instant messaging, or chat room messaging). In some embodiments, the digital display device  300  includes a web server component  470  that provides interfaces (such as those described with reference to  FIGS. 6A and 6B ) for interacting with the digital display device  300 . The digital display device  300  may also include a browser component  475  that fetches or retrieves content over an HTTP connection or other supported protocol (e.g., File Transfer Protocol (FTP), Secure Shell (SSH), RSS feeds, etc.). The digital display device  300  can also include other components, circuits, chips, etc. that enable the digital display device  300  to provide the functionality described herein as well as additional functionality. 
       FIG. 5  is a flow diagram of a process  500  for associating sources with display regions of a digital display device and providing content from sources on associated display regions. At block  505 , the digital display device is activated on a telecommunications network. The digital display device may be activated on a telecommunications network in any number of ways. For example, the digital display device may be activated by assigning it an additional identifier (e.g., a telephone number), or by marking as active a record in a database that is associated with the digital display device. In some embodiments, activation of the digital display device may be done at point-of-sale or prior to first use of the digital display device (e.g., the digital display device may have an identifier already assigned to it). In some embodiments, a user may activate the digital display device by accessing a website and providing an identifier to the website, which then activates the digital display device or causes it to be activated. At block  510  an indication of a desired association between a source of content and a display region of the digital display device is received from the user. For example, the user may indicate a desired association by accessing a website, identifying the user&#39;s digital display device, and assigning each of the display regions to a different source or group of sources used by an individual or group of individuals, by identifying the source(s) by their identifier(s). As another example, the user may indicate a desired association by using interfaces provided by the digital display device. At block  515  sources of content are associated with display regions of the digital display device. 
       FIGS. 6A and 6B  illustrate representative interfaces that enable a user to create associations between sources of content and display regions of a digital display device.  FIG. 6A  depicts an interface  600  that includes a confirmed sources region  605  displaying a number of sources  608  (shown individually as sources  608   a - f ). Each source  608  corresponds to a different actual source of content (e.g., a mobile phone, a digital camera, another digital display device, a digital video camera, a personal computer, a website, etc.). Each source  608  has an identifier (e.g., a telephone number, an IMSI, an e-mail address, an IP address, a MAC address, or other identifier) associated with it. For example, each of sources  608   a  and  608   f  can have an email address associated with it; source  608   b  can have a telephone number associated with it; and each of sources  608   d  and  608   e  can have a website address associated with it. The interface  600  also includes a digital display device region  610  which depicts the layout of the user&#39;s actual digital display device. The digital display device region  610  includes a number of display regions that are numbered 1-5. The numbered display regions correspond to the actual display regions of the user&#39;s digital display device. The user can create associations between a source  608  and a numbered display region by moving (e.g., dragging and dropping) the source  608  to the desired numbered display region. Alternatively, the user can move a numbered display region to the desired source or use some other method to create associations. As depicted, sources  608   d  and  608   c  are associated with numbered display region 1; source  608   b  is associated with numbered display region 2; source  608   a  is associated with numbered display region 3; sources  608   e  and  608   a  are associated with numbered display region 4; and source  608   f  is associated with numbered display region 5. More than one source  608  can be associated with a single numbered display region (as in the case of numbered display region 1) so as to enable the corresponding actual display region to display content from more than one source. Furthermore, a source  608  can be associated with more than one numbered display region (as in the case of source  608   a , which is associated with numbered display regions 3 and 4) so as to enable the content from the source  608  to be displayed on more than one corresponding actual display region (e.g., the content from the source  608  can be rotated or moved amongst the corresponding actual display regions). Creating associations in this way allows the user to specify the display region to which content from an individual source should be sent. Therefore, the interface  600  enables the user to have granular control over associations between sources of content and actual display regions. 
     The interface  600  also includes an unconfirmed sources region  615  displaying a number of unconfirmed sources  618  (shown individually as unconfirmed sources  618   a  and  618   b ). The user may be required to confirm unconfirmed sources  618  before the content from these unconfirmed sources  618  can be associated with the numbered display regions. Requiring the user to confirm unconfirmed sources thus prevents unconfirmed sources from having their associated content automatically displayed on the user&#39;s actual digital display device. The user can add new sources of content by selecting the “Add New Sources” button  630 , which can display a new interface (not shown) for adding new sources of content. 
       FIG. 6B  depicts another interface  650  that enables the user to create associations between contacts and display regions of the digital display device. The interface  650  includes a confirmed contacts region  655  displaying a number of contacts  658  (shown individually as contacts  658   a - f ). Each of the contacts  658  corresponds to an actual individual person. Each individual person may have one or more sources of content (e.g., a mobile phone, an email address, a digital camera, a website, a personal computer, etc., none of which are shown in  FIG. 6B ) associated with him or her. The interface  650  allows the user to associate all of (or some subset of) the sources of content associated with an individual with one or more display regions of the digital display device. Similar to the interface depicted in  FIG. 6A , the interface  650  includes a digital display device region  660  which depicts the layout of the user&#39;s actual digital display device. The digital display device region  660  includes a number of display regions that are numbered 1-5. The numbered display regions correspond to the actual display regions of the user&#39;s digital display device. The user can create associations between a contact  658  and a numbered display region by moving (e.g., dragging and dropping) the contact  658  to the desired numbered display region. Alternatively, the user can move a numbered display region to the desired contact or use some other method to create associations. As depicted, contacts  658   a  and  658   b  are associated with numbered display region 1; contacts  658   a  and  658   c  are associated with numbered display region 2; contact  658   d  is associated with numbered display region 3; contact  658   e  is associated with numbered display region 4; and contact  658   f  is associated with numbered display region 5. More than one contact  658  can be associated with a single numbered display region (as in the case of numbered display regions 1 and 2) so as to enable the corresponding actual display region to display content from the sources of more than one contact. Furthermore, a contact  658  can be associated with more than one numbered display region (as in the case of contact  658   a , which is associated with numbered display regions 1 and 2) so as to enable the content from the sources of the contact  658  to be displayed on more than one corresponding actual display region (e.g., the content from the sources of the contact  658  can be rotated or moved amongst the corresponding actual display regions). Creating associations in this way associates all of the sources of content associated with the individual (or just some subset of all of the sources of content can be associated with the individual) with one or more digital display regions. For example, contact  658   e  corresponds to an actual individual who may own, operate or use the following sources of content: a mobile phone, an email address, and a website. Each of the mobile phone, the email address, and the website, by virtue of contact  658   e &#39;s association with numbered display region 3, is now a source of content for the corresponding actual display region on the user&#39;s digital display device. Therefore, the interface  650  enables the user to associate all of the sources of content associated with an individual with an actual display region, which can be desirable if the user wishes to segregate the display regions on the digital display device on an individual basis. 
     The interface  650  also includes an unconfirmed contacts region  665  displaying one or more unconfirmed contacts  668 . The user may be required to confirm unconfirmed contacts  668  before the content from the sources of these unconfirmed contacts  668  may be associated with the numbered display regions. The user can add new contacts by selecting the “Add New Contacts” button  680 , which can display a new interface (not shown) for adding new contacts and their sources of content. 
     The interfaces  600  and  650  are not mutually exclusive and could be combined to allow the user to create associations between individuals and actual display regions while still allowing granular control on a source basis. For example, the user could create associations on an individual basis using the interface  650 . The user could then expand the contacts  658  to show the sources associated with each contact  658 , and then delete sources or move sources amongst the different numbered display regions. Those of skill in the art will understand that other methods of creating associations between sources of content and actual display regions are possible. 
     Returning to  FIG. 5 , at block  520  content is received from one or more of the sources associated with the different display regions. Some sources of content can be considered to be “pull” sources of content and others to be “push” sources of content. For example, referring back to  FIGS. 6A and 6B , website sources  608   d  and  608   e  can be considered to be “pull” sources in that website content (e.g., photos, videos, etc.) is usually (although not necessarily) “pulled” or downloaded from websites. As another example, email sources  608   a  and  608   f  can be considered to be “push” sources in that email content (e.g., text, photos, etc.) is usually (although not necessarily) “pushed” or sent from senders of emails to recipients of emails. After the user has saved the associations between the sources  608  and the numbered display regions (which can be done by selecting “Save Associations” button  625  or button  675 ), a notification that includes an identifier of the digital display device can be sent to “push” sources of content so as to enable the push sources of content to send content to the digital display device. For example, an email can be sent to email sources  608   a  and  608   f  to notify the email sources of the identifier (e.g., an email address) of the digital display device to which content can be sent. As another example, a text message can be sent to phone source  608   b  to notify the phone source  608   b  of an identifier (e.g., a telephone number) of the digital display device to which content can be sent. In some embodiments, each source is provided with the same identifier for the digital display device. In this case, the source of the content is determined by the source&#39;s identifier, and the content can thus be appropriately routed. In some embodiments, each source is provided with a different identifier for the digital display device. In this case, content that the source sends to the identifier can be recognized as coming from the source, and the content can thus be appropriately routed. Content can also be “pulled” from “pull” sources of content such as website sources  608   d  and  608   e , on a periodic, ad-hoc or other basis. Content can then be appropriately routed to the proper actual display region based upon the associations created using the interfaces  600  and/or  650 . It is of course possible for sources of content to be both “pull” and “push” sources. For these sources, either or both of the above methods can be used to obtain content. Those of skill in the art will understand that other methods of determining sources of content and routing the content to the actual display regions are possible. 
     Returning to  FIG. 5 , at block  525  the content is provided for display on the appropriate display regions. The digital display device can automatically display the content upon receipt substantially simultaneously in the appropriate different display regions. In some embodiments, the digital display device buffers received content by storing it in a storage medium before displaying the content. In some embodiments, the digital display device displays content in a slideshow fashion. 
     One skilled in the art will appreciate that the steps described above in the process  500  may be performed in an order other than the order described, and that additional or fewer steps may be performed. For example, an association between a source and a display region may be created when content is first received by the digital display device. One skilled in the art will also appreciate that the process  500  may be implemented by a server associated with the telecommunications network (e.g., an activation server) or by the digital display device itself, and/or that the interfaces  600  and  650  may be provided by a server associated with the telecommunications network (e.g., a web server) or by the digital display device itself. In some embodiments, one or more servers associated with the telecommunications network may implement the process  500 , provide the interfaces  600  and  650 , and store the data received via these interfaces. In these embodiments, the one or more servers associated with the telecommunications network act as intermediaries between the sources of content and the digital display device. In some embodiments, the digital display device implements the process  500 , provide the interfaces  600  and/or  650  (e.g., by its embedded web server), and stores the data received via these interfaces (e.g., in its storage medium). For example, the digital display device can display in each of the display regions an alphanumerical keyboard that the user can use to input identifiers identifying sources and/or to create associations. 
       FIG. 7A  is an isometric view of a digital display device  700  having three distinct displays. The digital display device  700  includes three distinct frames, labeled as frame  705   a , frame  705   b  and frame  705   c . Frame  705   a  is coupled to (i.e., attached to) frame  705   b  by a hinge  730   a , frame  705   b  is coupled to frame  705   c  by a hinge  730   b , and frame  705   c  is coupled to frame  705   a  by a hinge  730   c . Means other than the hinges  730  (e.g., magnetic attachments, connectors, etc.) may also be used to couple the frames  705  to each other. Accordingly, when the frames are appropriately moved with respect to each other around the hinge axes the digital display device  700  may assume a generally triangular configuration when viewed from above or below it. Each frame  705  includes a display: frame  705   a  includes a display  720   a , frame  705   b  includes a display  720   b , and frame  705   c  includes a display  720   c . Each display  720  may include one or more distinct display regions that may be associated with sources of content as described herein. The digital display device  700  also includes an antenna  715  coupled to, or carried by, the frame  705   c  that enables a wireless connection to a telecommunications network. The hinges  730  may be such that a frame  705  may be decoupled from, or detached from, another frame  705  to which it is coupled. For example, hinge  730   c  may permit frame  705   a  to be detached from frame  705   c . In a state where one frame  705  is detached from another frame  705 , the hinges  730  also permit the frames  705  that are still coupled to each other to move relative to each other. 
       FIG. 7B  is a side view illustrating the digital display device  700  where the frame  705   a  is decoupled from the frame  705   c  and the frames  705  are arranged in a generally linear configuration. One or more of the frames  705  may also include a hanger or other means for hanging (not shown in  FIG. 7B ) that is configured to enable the digital display device  700 , when the frames  705  are arranged in the generally linear configuration, to be attached to a surface (e.g., a surface of a wall). In some embodiments, the displays  720  may display content that differs based upon the configuration of the display device  700 . For example, when the display device  700  is in a non-linear configuration (e.g., in the generally triangular configuration), each display  720  may display a different item of content. When the display device  700  is arranged in the generally linear configuration, the displays  720  may display a single item of content, such as a panoramic image, that spans all of the displays  720 . As another example, in some embodiments, the frames  705  may be able to be completely detached from each other. In such embodiments, when the frames  705  are completely detached from each other, each display  720  in each frame  705  may display a different item of content. When one or more of the frames  705  are reattached to each other, the digital display device  700  may detect this reattachment and cause the displays  720  of the reattached frames  705  to display a single item of content that spans all of these displays  720 . 
     Although the digital display device  700  is shown as having three frames  705 , it may have more or fewer frames  705  (e.g., two frames  705 , four or more frames  705 ), each frame  705  having a display  720 . For example, the digital display device  700  may have four frames  705  coupled to each other and thus have a generally square configuration when viewed from above or below it. 
       FIG. 8A  is an isometric view of a digital display device  800  having the form of a cube. The digital display device  800  (referred to hereinafter as the digital display cube  800 ) has multiple faces  805 , including a first side face  805   a , a second side face  805   b , a top face  805   c , and three other faces (a third side face, a fourth side face, and a bottom face) that are not shown in the two-dimensional representation of  FIG. 8A . One or more of the faces may include multiple distinct display regions  820 . For example, the first side face  805   a  includes nine display regions  820 , several of which are labeled, individually, as display regions  820   a ,  820   b , and  820   i . The second side face  805   b  also has nine display regions, such as display region  820   j . The top face  805  also has nine display regions, such as display region  820   s . The two other side faces of the digital display cube  800  (not illustrated in  FIG. 8A ) also have nine display regions. Although the faces  805  are illustrated as having nine display regions, each or any of the faces  805  may have more or fewer display regions  820  (e.g., a single display region  820  on a face  805 , four display regions  820  on a face  805 , etc.). Although regions  820  are illustrated as having generally square shapes, the regions  820  may have other shapes, such as rectangular shapes, triangular shapes, trapezoidal shapes, L-shaped shapes, X-shaped shapes, irregular shapes, etc. 
     Although the digital display device  700  is depicted with three faces and the digital display cube  800  is depicted with five viewable faces (the bottom not being viewable when the digital display cube  800  is set on a surface), it will be appreciated that the techniques disclosed herein allow the construction of display devices having any number of faces that are set at angles with respect to one another. Moreover, the faces are not required to have a generally square shape, and may have other shapes such as rectangular shapes, triangular shapes, trapezoidal shapes, etc. For example, a display device may have four triangular-shaped viewable faces with a square bottom and take the form of a pyramid. Those skilled in the art will understand that the digital display device is therefore not limited to the form illustrated in e.g.,  FIG. 7A  and  FIG. 8A  and described herein. 
     The digital display cube  800  also has a bottom face (not illustrated in  FIG. 8A ) that allows the digital display cube  800  to be placed upon a surface (e.g., a generally horizontal surface). Because the bottom face is not viewable by a user when the cube is set on a surface, instead of a display region the bottom face may have non-skid feet, may provide access to batteries or other power supply, and may have one or more switches, displays, or other controls to operate the cube. For example, as described herein, the display regions  820  may be touch-sensitive, and the bottom face may include switches to activate and deactivate the touch-sensitive aspect of the display regions  820 . The digital display cube  800  includes a variety of components to enable the functions described herein. For example, the display cube includes a power supply, such as batteries or a transformer to allow the cube to be connected to an AC outlet. The digital display cube  800  also includes components that enable the transfer of digital media to and from the cube, such as computer-readable media storage drives (e.g., USB drives, other flash drives, etc.), telecommunications components (such as an antenna and modem) that enable wired or wireless connections, and components that identify the digital display cube on a telecommunications network (e.g., a SIM card, smart card, etc.). Components that the digital display cube  800  may include are discussed in more detail with reference to, e.g.,  FIG. 12 . 
       FIG. 8B  is a view of the face  805   a  of the digital display cube  800 . Each display region  820  can display a different item of content. For example, display regions  820   a - c  display images  825   a - c , respectively. Display region  820   d  displays a video clip  821 , display region  820   e  displays a website  822  and display region  820   f  displays a calendar interface  823 . Display region  820   g  displays an instant messaging session  824 , display region  820   h  displays an email interface  826  and display region  820   i  displays an address book interface  827 . Each of the display regions  820  can display any of the types of content described herein, as well as any other types of content suitable for display on an electronic display (e.g., text messages, interactive video games, televised content received over a wired or wireless connection, etc.). The digital display cube  800  may also receive content that has an audio component without a visual component (e.g., streamed music, an AM/FM radio feed, a Podcast, etc.). In such situation, the digital display cube  800  may play the audio component of the content, and display a screen saver or other visual aspect on one or more of the display regions  820 . 
       FIG. 8C  is another view of the face  805   a  illustrating how two or more display regions  820  may be merged to form a larger, merged, display region in which content may be displayed. As illustrated, the display regions  820   a ,  820   b ,  820   d  and  820   e  have been merged to form a merged display region. When display regions are merged, a primary display region may be designated for the purposes of designating the content that is to be enlarged to fill the merged display region, and secondary display regions may be explicitly or implicitly designated for the purposes of designating the content that is to be displaced or hidden. These designations may be done in various ways. For example, one or more of the display regions  820  may be touch-sensitive, and the user may touch a first display region (e.g., the display region  820   a ) to “grab” the content displayed in the first display region (e.g., image  825   a ) and drag it in a downwardly and rightwardly fashion (e.g., in the direction of arrow  830 ) to enlarge the content into display regions  820   b ,  820   d  and  820   e . Doing so displaces or hides the content formerly displayed in these display regions. As another example, a user may touch a first display region to designate it as the primary display region (e.g., the display region  820   a ) and then touch one or more second display regions to designate them as secondary display regions (e.g., the display regions  820   b ,  820   d  and  820   e ) that should be merged into or incorporated into the primary display region. Display regions that are non-contiguous may also be merged. For example, two non-contiguous display regions (e.g., display regions  820   a  and  820   c  on the same face, or two non-contiguous display regions on different faces  805 ) could be merged to form a merged display region that displays a single source of content. Those of skill in the art will understand that other ways of merging two or more display regions and/or enlarging content to fill two or more display regions may be used. 
       FIG. 8D  is another view of the face  805   a  illustrating how the content of two or more display regions  820  may be switched. As illustrated, the image  825   a , formerly displayed in display region  820   a , is displayed in display region  820   b , and the image  825   b , formerly displayed in display region  820   b , is displayed in display region  820   a . The content of two display regions may be switched by, for example, a user using two fingers (e.g., the thumb and the forefinger) to “grab” the content displayed in the display regions and then bringing the two fingers together to switch the positions of the content displayed in the display regions. Other methods of switching the positions of content in display regions  820  may of course be employed. 
       FIG. 8E  is another view of the face  805   a  illustrating other types of content that may be displayed in the display regions  820 . Display regions  820   a - c  are merged together to form a merged display region in which is displayed a news feed  840  containing one or more items of news. The news feed  840  may scroll across the three display regions that were merged to form a longer display that is more suitable for scrolling text. A user of the digital display cube  800  may subscribe to one or more news feeds or web feeds (e.g., RSS or Atom web feeds in XML format) that can be used to display content on the display regions. Display regions  820   h  and  820   i  are also merged to form a merged display region in which are displayed status messages  841   a  and  841   b . A user of the digital display cube  800  may subscribe to status messages or updates that indicate a status or presence of another individual or a group of individuals, such as status messages from social networking or micro blogging services (e.g., Facebook, Twitter, etc.), and have them displayed on the display regions. Other types of content delivered over data transmission networks such as the Internet and/or telecommunications networks in other ways may also be displayed on the display regions  820 . 
       FIG. 8F  is another view of the face  805   a  illustrating how a single item of content may be displayed multiple times in multiple display regions  820 . As illustrated, display regions  820   a ,  820   b ,  820   d  and  820   e  are merged to form a merged display region in which is displayed an image  842 . The image  842  is also displayed in three individual (i.e., non-merged) single display regions  820   c ,  820   g  and  820   h . The image  842  is also displayed in two merged display regions  820   f  and  820   i . Because the two display regions  820   f  and  820   i  form a merged display region that has a different aspect ratio (i.e., 1×2) than the aspect ratio of a single display region  820  (i.e., 1×1), the aspect ratio of the image  842  displayed is also changed. In other words, the image  842  is stretched (vertically in this case, although images may also be stretched horizontally) to display in the two display regions  820   f  and  820   i.    
       FIG. 8G  is another view of the face  805   a  illustrating how an image displayed in more than one display region  820  may be “mixed up” or “jumbled.” As illustrated, the image  843  is displayed across all nine display regions  820  of the left-hand face  805   a . Mixing up or jumbling the image  843  causes each of the different display regions  820  on the face  805   a  to randomly display a portion of the image  843 , as illustrated in the right-hand face  805   a . A user may mix up or jumble an image by, for example, touching a display region  820  to cause a contextual menu to be displayed that provides an option for mixing up or jumbling an image. An image may be mixed up or jumbled more than once, with each time resulting in a random arrangement of the portions of the image. In some embodiments, the digital display cube  800  includes an accelerometer that enables it to detect an inclination, a vibration, and/or a shock incurred by it. When the digital display cube  800  detects such a motion, it may cause the images displayed in one or more display regions  820  to be mixed up or jumbled. As another example, the user may mix up or jumble an image by touching display regions  820  on opposing portions of a face  805  with two or more fingers and by moving the fingers across the face  805 , thereby causing one or more portions of the image to be mixed up or jumbled. 
       FIG. 8H  is another isometric view of the digital display cube  800  illustrating how display regions  820  on two or more faces  805  may be merged in order to cause content to wrap around two or more faces. For example, display regions  820   m ,  820   n  and  820   o  on face  805   b  and display regions  820   d ,  820   e  and  820   f  on face  805   a  have been merged to form a merged display region for the display of a status message  849 . The corresponding display regions on the other two side faces  805  of the digital display cube  800  may also be merged into this merged display region such that the status message  849  wraps all the way around the digital display cube  800 . As another example, display region  820   k  on face  805   b  and display region  820   v  on face  805   c  are merged to form a merged display region for the display of a video clip  869 . As another example, display regions  820   a ,  820   l  and  820   y  on faces  805   a ,  805   b  and  805   c , respectively, are merged to form a merged display region in which is displayed a digital image  879  that is stretched to display in all three display regions  820 . The display regions  820  of the digital display cube  800  can be merged or configured in various ways to display content in numerous different ways. 
       FIG. 9  is a side view of a face  905  of a digital display cube  900  configured in accordance with an embodiment of the invention. The face  905  carries nine display regions  920  (several of which are individually labeled as display regions  920   a - c ). The face  905  also carries audio output components  930  (shown individually as audio output components  930   a  and  930   b ). The audio output components are left and right stereo speakers that are configured to produce sound. The digital display cube  900  also includes an audio input component  940  (e.g., a microphone) that is configured to receive sound. The display regions  920  may be touch-sensitive. Touch-sensitive display regions  920 , when activated or actuated by a user (e.g., by touch and then selection of a contextual menu option), are configured to cause the digital display cube  900  to initiate a real-time communication session with the source associated with the content that is displayed on the touch-sensitive display region  920  at the time the touch-sensitive display region  920  is touched. For example, if an image of an individual who uses or operates a source (e.g., a digital photograph of the individual) is displayed in a particular display region  920 , the user can touch the particular display region  920  to cause the digital display cube  900  to initiate a real-time communication session (such as a voice call, a video call (e.g., a Skype video/voice call), an e-mail, a text message, an instant messaging session or other communication) with that individual. Upon successfully reaching the individual after initiating a voice call, the user can speak into the audio input component  940  and hear the individual via sound generated by the audio output components  930 . The user can adjust the volume of the sound generated by the audio output components  930  by utilizing up and down buttons  935  or via the touchscreen. When the user desires to end the call, the user can again activate or actuate the touch-sensitive display region  920  to cause the digital display cube  900  to end the initiated voice communication. In some embodiments, a display region  920  is associated with a source or sources used or operated by multiple individuals. For example, a display region  920  may be associated with a source used or operated by two individuals. The user can touch the display region  920  associated with the source to initiate real-time communications with the individuals (e.g., three-way calling; a chat room session, an instant messaging session, a live video conferencing session, etc.). 
     In some embodiments, if an image of an individual who uses or operates a source (e.g., a digital photograph of the individual) is displayed in a particular display region  920 , the user can “tap” the particular display region  920  with a mobile device of the user (e.g., using methods described in the previously referenced PCT/US08/54793). This causes the digital display cube  900  to transfer to the user&#39;s mobile device a telephone number of the individual displayed in the particular display region  920 . The user&#39;s mobile device can then automatically initiate a telephone call to the individual. Alternatively or additionally, the digital display cube  900  may transfer other identifying information (e.g., an email address of the individual, an instant message identifier of the individual, etc.) to the user&#39;s mobile device. The user&#39;s mobile device can then automatically initiate an appropriate real-time communication (e.g., an email message, an instant message, a text message, etc.) with the individual using the identifying information transferred to it by the digital display cube  900 . 
     In some embodiments, as described with respect to the digital display device  300 , while a user is engaged in a real-time communication with a first individual, the user can initiate a second real-time communication session with a second individual who uses or operates a second source, and conference the two individuals together into a group real-time communication session using features provided by the digital display cube  900 . 
     The digital display cube  900  also includes a camera  925  that is configured to capture still or moving images for transmittal to the telecommunications network and ultimately to a remote recipient, and a button (not shown in  FIG. 9 ) configured to activate the camera  925 . For example, a user can position himself or herself in front of the camera  925  and activate the camera  925  (e.g., by pressing the button, utilizing a remote or otherwise successfully triggering the digital display device&#39;s functionality) to capture a still or moving image of himself or herself. The user can then touch a touch-screen display region  920  to send the captured image to the individual using or operating the source associated with the touch-screen display region  920 . In some embodiments, the user can activate the camera  925  before or during an initiated real-time communication session and cause the digital display cube  900  to transmit one or more still or moving images over the telecommunications network to a remote recipient. A user of the digital display cube  900  can thus provide content to another user, such as another user of another digital display cube. During the real-time communication session, the digital display cube  900  displays content (e.g., video, still images, etc.) on a face  905  from the other user with whom the user is communicating. In some embodiments, during a real-time communication session, one or more of the display regions  920  on the face  905  can function to display content (e.g. video, still images, etc.) from the other user with whom the user is communicating (e.g., in a picture-in-picture, video-in-video, picture-in-video or video-in-picture fashion). This enables the user of the digital display cube  900  to view both the content associated with the other user as well the content that the other user can view on their respective device (e.g., the content captured by the camera  925 ). 
     In some embodiments, the digital display cube  900  may be used to facilitate a conference or group communication between a number of individuals. For example, if each of the side faces of the digital display cube contained a camera  925 , the digital display cube  900  may be placed in the center of a table or a desk and users wishing to participate in the group communications session would sit in positions surrounding the digital display cube  900 . The cameras  925  would transmit still or video pictures of the individuals to the other party or parties that receive the communication. The individuals surrounding the digital display cube  900  may view the party or parties to which they are communicating on the display regions  920 . If there is only one receiving party, all nine of the display regions  920  may be merged to display a single image or video of the receiving party. If there are multiple receiving parties, one or more display regions  920  may be associated with each receiving party. 
       FIG. 10  illustrates a representative interface  1000  for creating associations between sources of content and display regions of a digital display cube. The interface  1000  includes a confirmed sources list  1004  displaying a number of sources  1008  (shown individually as sources  1008   a - m ). Each source  1008  corresponds to a different actual source of content. Sources of content may include, but are not limited to, a mobile phone, a digital camera, another digital display device, a digital video camera, a personal computer, a website, a video clip, a photo set or collection of photos, an individual photo, a calendar application, an address book application, an email application, a news feed, a status feed, etc. Each source  1008  has an identifier (not shown) associated with it that allows content to be sent to or received from the source. Identifiers include, but are not limited to, a telephone number, an IMSI, an e-mail address, an IP address, a MAC address, a website address, a Uniform Resource Identifier (URI) or other identifier. For example, source  1008   a  may have an email address associated with it; source  1008   b  may have a telephone number associated with it; and each of sources  1008   d ,  1008   e ,  1008   f  and  1008   g  may have a URI (e.g., a website address) associated with it. The interface  1000  also includes a virtual representation  1010  that depicts the layout of the user&#39;s physical digital display cube. The virtual representation  1010  may be rotated or spun by use of controls  1035 . The representation  1010  includes display regions that correspond to the display regions on the user&#39;s actual digital display cube (i.e., each depicted display region on the virtual representation maps to one of the display regions of the physical display cube). The user can create associations between a source  1008  and a display region by dragging and dropping the source  1008  to the desired display region. Alternatively, the user can move a display region to the desired source, assign a code to each source that maps to a display region, or use some other method to create associations. As shown in  FIG. 10 , each display region or regions in the virtual representation  1010  contains a number which correlates with numbers associated with each source  1008  in the confirmed source list  1004 . 
     A source may be associated with a merged display region consisting of two or more individual display regions (e.g., two display regions on a same face, or two display regions on two different contiguous or non-contiguous faces). For example, source  1008   i , which corresponds to a photo, is associated with a merged display region consisting of the three lower display regions on face  1005   b  of the virtual representation  1010 . As another example, source  1008   f , which corresponds to a status feed, is associated with a merged display region consisting of the three middle display regions on face  1005   b  and the three middle display regions on face  1005   a  of the representation  1010 . The association across two faces allows the status feed content corresponding to the source  1008   f  to be displayed on the actual digital display cube in scrolling fashion from one face to another. As another example, source  1008   j , which corresponds to a set of photos or collection of photos, is associated with a merged display region consisting of three contiguous display regions, one on face  1005   a , one on face  1005   b  and one on face  1005   c . Accordingly, the photos in source  1008   j  will be stretched or constrained to display in all three display regions. A source may also be associated with two distinct non-merged display regions. For example, source  1008   e , corresponding to an instant messaging session, is displayed in each of two upper display regions on face  1005   a . These two display regions are non-merged, meaning that an instance of the content corresponding to the instant messaging session will be displayed in each of the two display regions. More than one source  1008  may be associated with a single display region on the virtual representation  1010  so as to enable the corresponding physical display region to display content from more than one source. 
     Although not depicted in  FIG. 10 , a control may be provided to allow a user to specify that a display region is to display content from a randomly selected source  1008 . A user may also specify that a source is to be rotated or periodically moved from one display region to another display region. The user can save the created associations by selecting a “Save Associations” button  1025 . The user can clear the created associations to start over by selecting a “Clear All Associations” button  1028 . Creating associations using the interface  1000  allows the user to specify a display region to which content from an individual source of content should be sent or received. Therefore, the interface  1000  enables the user to have granular control over associations between sources of content and display regions of an actual digital display cube. 
     The interface  1000  also includes an unconfirmed sources region  1015  displaying a number of unconfirmed sources  1018  (shown individually as unconfirmed sources  1018   a  and  1018   b ). Unconfirmed sources may be a result of unknown or not-approved sources sending a request to a user to send content to the user. The user may be required to confirm unconfirmed sources  1018  (e.g., by selecting the corresponding confirm button  1020 ) before content from the unconfirmed sources  1018  will be associated with the numbered display regions. When the user confirms an unconfirmed source  1018 , it may be automatically added to the confirmed sources region  1004 , or the user could be prompt to add it to the confirmed sources region  1004 . Requiring the user to confirm unconfirmed sources  1018  thus prevents unconfirmed sources  1018  from having content automatically displayed on the user&#39;s physical digital display device. The user can manually add new sources of content by selecting an “Add New Sources” button  1030 , which displays an interface (not shown) for adding new sources of content. 
       FIG. 11  depicts another interface  1100  that enables the user to create associations between contacts and display regions of a digital display cube. Each contact  1108  corresponds to an actual individual person. The interface  1100  includes a confirmed contacts list  1104  displaying a number of contacts  1108  (shown individually as contacts  1108   a - d ). Each individual person may have one or more sources of content  1110  (e.g., a mobile phone, a digital camera, another digital display device, a digital video camera, a personal computer, a website, a video clip, a photo set or collection of photos, an individual photo, a calendar application, an address book application, an email application, a news feed, a status feed, etc.) associated with him or her. For example, the individual corresponding to contact  1108   a  has associated with him or her a photo set  1110   a , a status feed  1110   b , a first website  1110   c  and a second website  1110   d , and the individual corresponding to contact  1108   b  has associated with him or her a status feed  1110   e , a website  1110   f , and a photo set  1110   g . The sources of content  1110  associated with contacts  1108   c  and  1108   d  are not displayed but can be by selecting arrows  1125   c  and  1125   d , respectively. The contact  1108   a  also has two associated buttons  1115   a  and  1120   a  that enable the user to add new sources of content and modify existing sources of content, respectively, for this contact. The contact  1108   b  also has two associated buttons  1115   b  and  1120   b  that enable the user to add new sources of content and modify existing sources of content, respectively, for this contact. Each source of content  1110  has an identifier (not shown) associated with it that allows content to be sent to or received from the source. Identifiers include, but are not limited to, a telephone number, an IMSI, an e-mail address, an IP address, a MAC address, a website address, a URI or other identifier. 
     The interface  1100  allows the user to associate all of (or some subset of) the sources of content  1110  associated with an individual with one or more display regions of the user&#39;s actual digital display cube. Similar to the interface depicted in  FIG. 10 , the interface  1100  includes a virtual representation  1111  that depicts the layout of the user&#39;s actual digital display cube. The virtual representation  1111  may be rotated or spun by use of controls  1135 . The virtual representation  1111  includes display regions that correspond to the display regions on the user&#39;s actual digital display cube (i.e., each depicted display region on the virtual representation  1111  maps to one of the display regions of the actual digital display cube). The user can create associations between a contact  1108  (or a source of content  1110 ) and a display region by dragging and dropping the contact  1108  (or a source of content  1125 ) to the desired display region. Alternatively, the user can move a display region to the desired contact (or to a source of content  1110 ), assign a code to each contact (or source of content  1110 ) that maps to a display region, or use some other method to create associations. As shown in  FIG. 11 , each display region or regions in the virtual representation  1111  contains a number which correlates with numbers associated with each contact  1108  (or with each source of content  1110 ) in the confirmed contact list  1104 . 
     The interface  1100  allows the user to associate an entire face of the user&#39;s actual digital display cube with the sources of content  1110  associated with a specific individual. As illustrated in  FIG. 11 , the virtual representation  1111  depicts that the face  1105   c  is associated with contact  1108   b . The user&#39;s actual digital display cube could rotate randomly among the sources of content  1110  associated with that contact  1108   b , such as the individual&#39;s status feed  1110   e , a website  1110   f  of the individual, and a set of photos  1110   g  associated with the individual. For example, the actual digital display cube could normally display in the display regions on the face  1105   c  the set of photos  1110   g  associated with the individual. When the actual digital display cube receives status updates for the individual (source of content  1110   e ), it could display them in one or more specific display regions on the face  1105   c . After a specific period of time, the displayed status updates could fade out or slowly disappear, and the normally displayed set of photos  1110   g  could fade in or reappear and resume being displayed in display regions on the face  1105   c.    
     Although not depicted in  FIG. 11 , a control may be provided to allow a user to specify that a display region is to display content from a randomly selected contact  1108  (or from a randomly selected source of content  1110 ). A user may also specify that a contact  1108  (or a source of content  1110 ) is to be rotated or periodically moved from one display region to another display region. The user can save the created associations by selecting a “Save Associations” button  1125 . The user can clear the created associations to start over by selecting a “Clear All Associations” button  1128 . Creating associations using the interface  1100  allows the user to specify a display region to which content from a contact  1108  (or content from a source of content  1110 ) should be sent or received. Therefore, the interface  1100  enables the user to have granular control over associations between contacts  1108  (or sources of content  1110 ) and display regions of an actual digital display cube. 
     The interface  1000  also includes an unconfirmed contacts region  1165  displaying a number of unconfirmed contacts  1168  (shown individually as unconfirmed sources  1168   a  and  1168   b ). Unconfirmed contacts  1168  may be a result of unknown or not-approved contacts sending a request to a user to send content to the user. The user may be required to confirm unconfirmed contacts  1168  (e.g., by selecting the corresponding confirm button  1170 ) before content from the unconfirmed contacts  1168  may be associated with the display regions of the virtual representation  1111 . When the user confirms an unconfirmed contact  1168 , it may be automatically added to the confirmed contacts region  1104 , or the user could be prompt to add it to the confirmed contacts region  1104 . Requiring the user to confirm unconfirmed contacts  1168  thus prevents unconfirmed contacts  1168  from having content automatically displayed on the user&#39;s actual digital display cube. The user can manually add new contacts by selecting an “Add New Contacts” button  1130 , which displays an interface (not shown) for adding new contacts. 
     The interfaces  1000  and  1100  are not mutually exclusive and could be combined to allow the user to create associations between individuals and actual display regions while still allowing granular control on a contact basis. For example, the user could create associations on an individual basis using the interface  1100 . The user could then expand the contacts  1108  to show the sources of content  1110  associated with each contact  1108 , and then delete sources of content  1110  or move sources of content  1110  amongst the different display regions. Those of skill in the art will understand that other methods of creating associations between sources of content and actual display regions are possible. 
     One skilled in the art will appreciate that a process for creating associations between content sources and display regions of a digital display cube may be implemented by a server or computing device (e.g., an activation server) or by the digital display cube itself. One skilled in the art will also appreciate that the interfaces  1000  and/or  1100  may be provided by a server or computing device (e.g., a web server) or by the digital display cube itself. If provided by a server or computing device, the interfaces  1000  and/or  1100  may be generated and presented to a user on a website operated by a manufacturer of a display device, by a service provider that provides telecommunications or other services to a purchaser of a display device, or by any other third-party. When the interface is presented on a website, the one or more servers or computing devices generating the interface may connect with other systems that act as intermediaries between the sources of content and digital displays, and may provide the interface  1000  and/or  1100 , store data received via the interface, communicate changes made via the interface to display devices, and route content between sources of content and display devices in accordance with the received settings. In some embodiments, the digital display cube implements the association creation process, provides the interfaces  1000  and/or  1100  (e.g., by an embedded web server), and stores the data received via these interfaces (e.g., in a storage medium). For example, the digital display cube can display in one or more display regions an alphanumerical keyboard that the user can use to input identifiers identifying sources and/or to create associations. Alternatively or additionally, a user may use another wireless device (e.g., a wireless keyboard, a mobile device, a personal computer with a wireless card and/or a Bluetooth interface) to provide input to the digital display device to identify sources and/or to create associations. 
       FIG. 12  is a schematic view of components of the digital display cube  900  illustrated in  FIG. 9 . The digital display cube  900  includes various components that enable it to provide the functionality described herein as well as additional functionality. These components include an audio input component  1205  (e.g., microphone) and an audio output component  1210  (e.g., speakers). A user input component  1230  (e.g., buttons, alpha-numerical keyboard, etc.) enables the user to interact with the digital display device (e.g., adjust speaker volume, access stored content, adjust configuration settings, etc.). A camera component  1245  (e.g., digital camera) captures images (e.g., still or moving images). A storage medium component  1235  (e.g., hard drive, flash memory, memory card, etc.) stores content and other data (e.g., processing instructions, configuration settings, etc.). A processor  1250  executes processing instructions. The digital display cube  900  also may include a SIM card interface  1220 , which enables the digital display cube  900  to receive a SIM card for purposes of accessing a GSM/GPRS/EDGE/UMTS telecommunications network, and an antenna  1240  for transmitting and receiving wireless signals. The digital display cube  900  also includes a power source  1255  (e.g., batteries, AC/DC converter, etc.). 
     The digital display cube  900  also includes a communication component  1225 , which may include a GSM/GPRS/EDGE/UMTS component  1225   a , a Bluetooth component  1225   b , a Wi-Fi component  1225   c  and/or a wired component  1225   d  (e.g., RJ-11 port, Ethernet port, etc.). The Bluetooth component  1225   b  and/or the Wi-Fi component  1225   c  enable the digital display cube  900  to transmit and receive wireless signals in the 2.4 GHz Industrial Scientific Medical (ISM) band. Other wireless protocols (e.g., Mobile Broadband Wireless Access (MBWA), Ultra Wideband (UWB), ZigBee and other protocols) may also be supported. The digital display cube  900  also includes an infrared component  1265  that enables communication over an infrared spectrum (e.g., for communicating with a remote control that operates the digital display cube  900 ). 
     The digital display cube  900  also includes eight display face components  1259  (although only three—display face components  1259   a ,  1259   b  and  1259   h —of which are shown). Each display face component  1259  corresponds to a face  905  of the digital display cube  900 . Each display face component  1259  may comprise one or several touchscreen liquid crystal displays  1260  (shown individually as touchscreen displays  1260   a - i ), each of which corresponds to a display  920  on a face  905  of the digital display cube  900 . Alternatively, the digital display cube  900  may include a single touchscreen liquid crystal display that is mapped via software to provide the various display regions. The displays  1260  display content associated with the display regions and are touch-activated to provide varied functionality. In addition to displaying content, the touchscreen displays  1260  can display user interfaces (e.g. alphanumerical keyboard, buttons for selecting options, menus, etc.) that enable users to interact with the digital display cube  900 , either by using the touchscreen displays or by a remote. 
     The digital display cube  900  also includes a routing component  1280  that automatically routes received content to the appropriate display  1260 . The digital display cube  900  also includes a real-time communication component  1285  (e.g., hardware and/or software for audio and/or video communication, hardware and/or software for text messaging, instant messaging, or chat room messaging). In some embodiments, the digital display cube  900  includes a web server component  1270  that provides interfaces (such as those described with reference to  FIGS. 10 and 11 ) for interacting with the digital display cube  900 . The digital display cube  900  may also include a browser component  1275  that fetches or retrieves content over an HTTP connection or other supported protocol (e.g., File Transfer Protocol (FTP), Secure Shell (SSH), RSS feeds, etc.). 
     The digital display cube  900  also includes an accelerometer component  1286  that measures acceleration and gravity induced reaction forces. When the accelerometer component  1286  detects acceleration, the digital display cube  900  may change and/or rearrange content on one or more of the display regions  920 , update content, jumble or mix up content on one or more of the display regions  920 , switch between connected users, etc. In some embodiments, the digital display cube  900  also includes a docking component  1287  that enables it to dock with a docking station (e.g., for transferring content to the digital display cube  900 , for charging its batteries, etc.). 
     In some embodiments, the digital display cube  900  also includes a presence detection component  1288  that enables it to detect the proximal presence of an individual, and display content associated with that individual. For example, the presence detection component  1288  may include a polling radio frequency identification (RFID) transceiver that polls proximal RFID transponders or RFID tags (included in e.g., mobile devices such as phones), receives identifiers from such RFID transponders, determines an individual based upon the identifier, and displays content associated with that individual or appropriate to that individual. As an example of this functionality, the digital display cube  900  may detect that a mobile device of an individual is proximate. The digital display cube  900  may request that the mobile device provide its telephone number to the digital display cube  900 . The digital display cube  900  can then use the telephone number to look up (e.g., in an index stored on the storage medium component  1235 ) the individual associated with that telephone number. If the individual is a confirmed contact, the digital display cube  900  can then determine sources of content associated with that individual, and display the content on one or more displays  920  of one or more faces  905  of the digital display cube  900 . 
     The digital display cube  900  can also include other components, circuits, chips, etc. that enable it to provide the functionality described herein as well as additional functionality. 
     From the foregoing, it will be appreciated that specific embodiments of the invention have been described herein for purposes of illustration, but that various modifications may be made without deviating from the spirit and scope of the invention. Accordingly, the invention is not limited except as by the appended claims.
