In particular, the disclosure relates to a water slide system including a circumferentially closed slide tube that is translucent or transparent, at least in sections, and in which a slide surface that is wettable with water and extends in a slide direction is provided for a user, wherein lighting features that are visible from the interior of the slide tube are situated on the outer side of the slide tube in order to achieve optical effects in the interior of the slide tube. The discosure further relates to a method for operating a water slide system. 
     Description of Related Art 
     Water slide systems comprising a circumferentially closed slide tube are well known. For generating light effects in the interior of the tube, it is known to equip the outer side of the slide tube with separate light emitting diodes (LEDs), for example for simulating a starry sky, or with an LED strip. The achievable optical light effects do not extend beyond blinking or continuous light effects.

     A tube is known from U.S. Pat. No. 5,482,510 A which, among other things, may be slid through. Various light effects such as stereoscopic light may be achieved to evoke various feelings in the user. 
     A water slide having an audiovisual entertainment system is known from WO 2006/116176 A2, wherein images may be projected into a water curtain by means of a projector. 
     BRIEF SUMMARY 
     In view of the above-mentioned prior art, the disclosure provides a water slide system including at least one slide tube section via which the slide experience for the user is improved by implementing elaborate optical effects. The aim in particular is to provide the water slide system in such a way that the subjective feeling of acceleration or sliding speed and/or a feeling of direction are/is influenceable. Moreover, the system may provide a method for operating such a water slide system. 
     In an aspect, the lighting features are formed from pixels, which may include LEDs, for example, arranged in a matrix of at least one screen module (LED module or digital image area), which in turn is arranged and/or designed in the manner of a shell on the outer side of the slide tube and extending over a circumferential section of the slide tube, and which is actuatable and/or actuated in order to display, for example, moving two-dimensional and/or stereoscopic images that are curved in the circumferential direction. 
     In an aspect, a water slide is designed, at least in sections, as a screen slide, i.e., in such a way that two-dimensional and/or stereoscopic, preferably moving, images that are curved in the circumferential direction of the slide tube are displayable from the interior of the slide tube, i.e., are visible to a user when sliding, via which, for example, the subjective feeling of acceleration and/or velocity and/or slide direction of the user may be influenced. As a result of an image that is uniform or repeating, or which moves or shifts opposite the slide direction, for example in the form of moving arrows or the like, in particular over a time period of several seconds, it is thus possible to achieve an impression of speed that is greater than the actual sliding speed. Additionally or alternatively, it is possible to display visually changing light and/or color effects in the form of two-dimensional and/or stereoscopic stationary images or videos (images moving in two dimensions and/or stereoscopically). In one aspect, the image may extend over a circumferential angle of at least 120°, preferably at least 180°, and/or over a length of at least one meter, particularly preferably over at least five meters, even more preferably over at least 10 meters or longer, in the slide direction. The resolution of a screen module may be preferably at least 100×100 pixels, and more preferably 250×250 pixels. In an aspect, multiple screen modules having such a resolution may be provided, for example, next to one another in the circumferential direction and one behind the other in the slide direction. The screen modules may be actuated in such a way that an overall image is displayable with the screen modules, for which purpose the multiple screen modules are connected, preferably in a signal-conducting manner, to a so-called video splitter that divides an overall image over the multiple screen modules, i.e., into partial image sections. 
     As the result of images moving in the circumferential direction, it is additionally or alternatively possible to create a subjective turning device pressure that suggests to the user that he/she is moving in the circumferential direction, i.e., to the right or left. It is also possible to impart the subjective impression of a slower sliding speed by moving image content in the slide direction. To achieve this effect, identical or similar image contents are preferably selected, at least over a certain time period, which progress from pixel to pixel in the desired direction, i.e., appropriately moved forward by actuating features on a screen module and preferably shifted from screen module to screen module. 
     In order for a sharp image to result for the user, the slide tube may have a translucent or transparent design in sections, in particular in the areas that are provided with the at least one screen module. Acrylic glass, for example, may be used for a transparent design. 
     However, a translucent, for example opaque, design may be preferred in some implementations, since this approach may allow, for example, only the pixels of the at least one screen module to show through and be visible to the user, and the remaining module technology may remain concealed. In particular materials such as glass-fiber reinforced plastic (GFRP), polycarbonate, and Plexiglas may be suitable for a translucent design. 
     Surprising synergistic effects may also result, in addition to the novel slide experience and the achievable optical effects. Due to integration of the at least one screen module into a water slide system, good heat dissipation from the pixels, preferably composed of LEDs, may be ensured in an innovative manner, such as when the pixels directly contact the outer side of the slide tube, i.e., lie against it on the outside. As a result of the direct contact, heat may be released to the translucent or transparent slide tube material. This material is in turn may be cooled, at least in sections, by the slide water present in the water slide or the slide tube. The screen module (LED module/digital image area) may preferably have the following minimum specifications: Flex display and/or LED pixel pitch of 7 mm, and/or a pixel density ≧15,876 per square meter, and/or a brightness &gt;5000 nits, and/or a power consumption of 250 W/m 2 , and/or a viewing angle of 120°, and/or a refresh rate 1800 Hz, and/or a moisture resistance 99%, and/or 16,000,000 colors. 
     Thus, a curved screen may thus be used, for example, to directly surround the slide tube and may be cooled from the front side with water. 
     Another desirable effect may include that water flow or water film, which from the user&#39;s viewpoint, may occur in front of the image, may bring about interesting streak effects that are intensified by suitable images or distortion techniques, or may be at least partially be compensated for if needed. 
     Thus, one example water slide system designed according to the disclosure may have a slide tube that is directly associated with a curved image area composed of a plurality of pixels arranged in a matrix in order to provide the user with numerous novel visual impressions. An arrangement of pixels in a matrix is understood to mean, for example, that pixels may be situated along two axes that are spanned by an angle, in particular about 90°, one of the axes being curved in the circumferential direction of the slide tube, in particular having a radius of curvature that corresponds to the radius of curvature of the slide tube. The pixels may be arranged in rows and columns and may be individually actuated. The rows may preferably extend in parallel to the slide direction, while the columns of pixels may be oriented perpendicularly thereto, in order to follow the curvature of the slide tube in the circumferential direction or map the same, such as in a stepped manner. To ensure an image, which may be curved in the circumferential direction and which at the same time may further extend in two-dimensions and/or stereoscopically in the slide direction, is properly viewable, the screen module used may have a shell-like design. This approach may be achieved in a particularly innovative manner by connecting submodules (module surface sections) that may in each case be flat so that they extend, for example, in an articulated manner, in each case with two adjacent submodules enclosing an angle. With a preferred articulated connection of submodules or partial screen sections of a module, the module may be adapted to the individual radius of different slide tubes in a particularly innovative manner. 
     As mentioned, the water slide system designed according to the disclosure may include at least one, preferably shell-like, screen module suited for displaying curved two-dimensional images, for example, in the form of moving images (video). One embodiment of the water slide system may provide stereoscopic images that are displayable and/or displayed, for example, in the form of stereoscopic videos, on at least one screen module, and in some implementations, preferably multiple screen modules. In this way, a spatial impression of depth that is not physically present (except for possibly the curvature) may be imparted to the user. The principle of stereoscopy is based on the fact that a (human) user observes his/her surroundings simultaneously from two viewing angles through his/her two eyes. In this way, the brain of the user is able to efficiently associate a distance with all objects being observed, or to obtain a spatial image of his/her surroundings, without having to keep the head in motion. The stereoscopy, or in this specific case the stereoscopic actuation, of the at least one screen module only allows different (in each case two-dimensional) images to be brought into the left eye and the right eye of the user from two slightly different viewing angles. For this purpose, there are different methods known in the related art, but which have not been applied thus far within the scope of a water slide system. As explained in greater detail below, in one aspect, a shutter method, or alternatively a three-dimensional polarization system method, may be used, whereby, as explained in greater detail below, the user may wear appropriate channel separation features, such as glasses, while sliding. With this approach, images may be displayed simultaneously or in succession, depending on the applied method, and viewed by the eyes separately, in a defined manner. The screen module may be designed and actuated as a so-called stereo display to allow stereoscopic vision for the user, depending on the method, with or without channel separation aids, such as appropriate glasses (e.g., shutter glasses or polarized filter glasses). 
     In an aspect, the waterslide may include tubes having a circular or approximately circular cross section or partial such cross section, for example, having a diameter in a range between about 60 cm and 300 cm. Alternatively, it is also possible to use slide tubes having a circumferential contour that is different from a circular shape, for example oval slides, in which case a maximum is preferably selected from a value range of about 60 to 350, and a minimum diameter, extending perpendicularly thereto, is selected from a value range of about 50 to 300. 
     In one embodiment, images may be displayable in different ways, for example by changing colors using screen modules. This aproach may be achievable in a particularly innovative and simple manner by forming the pixels from multicolored light emitting diodes, such as two, three, or more differently colored LEDs, as is basically known, for example, from LED displays for large events. 
     In an aspect, the LEDs that are used within the scope of the screen module may be able to display a color spectrum of 16,000,000 colors or more. 
     In one embodiment of a water slide system, at least one screen module may be connected in a signal-conducting manner to actuating features, which may include a video processor, for example, in order to supply the screen module with a suitable actuating signal for displaying two-dimensional and/or stereoscopic, in particular multicolored, images. The actuating features may preferably be designed in such a way that they have a terminal for connection to an image source, such as a video source, and/or are connected to an image source. The image source, in particular video source, may be a media server, for example, or in the simplest case may be a suitable playback device, such as a video player, preferably in the form of a Blu-ray player or a DVD player. The input signal, with the aid of the actuating features, is then converted into a preferably multiplexed control signal for actuating the screen module. 
     It is particularly advantageous when the water slide system comprises multiple screen modules, not just a single screen module. In an aspect, the multiple screen modules, for example, having a shell-like design in each case, may be arranged adjacent one another sequentially in the circumferential direction in order to thus cover a preferably large circumferential angle, such as 120° or more, more preferably at least 180°, and very particularly preferably at least approximately 360°. 
     In addition or as an alternative to an arrangement of multiple screen modules in the circumferential direction, it is possible to arrange multiple screen modules one behind the other in the slide direction. 
     It has been found to be particularly advantageous when the actuating features for actuating the screen modules include a video splitter with which multiple screen modules arranged next to one another in the circumferential direction and/or one behind the other in the slide direction so as to be actuatable or actuated for displaying a moving overall image. Thus, image information provided by an image source (signal source) or video source may be divided over multiple screen modules, such as in a matrix confirguration. 
     In an aspect, the multiple screen modules, having a shell-like design in each case (analogously to the pixels of a screen module) may be arranged in a matrix and thus form an overall screen that, as explained in greater detail below, is preferably actuatable for displaying an overall image. 
     In an aspect, the actuating features may be designed in such a way that an image that extends over all pixels of a screen module and/or an image portion that extends over multiple screen points (in particular arranged in a matrix) may be displaceable from pixel to pixel and/or from screen module to screen module in the circumferential direction of the slide tube and/or in the slide direction and/or opposite the slide direction. In this manner, image content that is constant, in particular at least with regard to the image content contours, may be further displaced on a screen module, such as beyond the module boundaries, in at least one of the above-mentioned directions or in a resultant, for example diagonal, direction from a plurality of the above-mentioned directions, thus imparting an impression of motion. 
     It is thus possible, for example, to further displace a serrated geometry, extending in the circumferential direction, in the same or opposite direction as the slide direction and thus display a movement sequence. This approach may be particularly used, for example, when the above-mentioned image content (or some other image content) repeats, and the repetition as a whole is moved in the same or opposite direction as the slide direction. It is also possible to further displace image content, extending in the slide direction, in the circumferential direction. 
     As discussed above, in an example implementation, a shell-like screen module may be implemented that has multiple module surface sections that include pixels arranged in a matrix in a shared straight plane.; Alternatively, the arrangement may include only single rows of pixels within two adjacent flat module surface sections enclosing an angle, so that in the entirety of the module surface sections form a shell-like screen module that extends around the slide tube in the circumferential direction results. In one embodiment of the screen module, the module surface sections may be articulatedly connected to one another, thus allowing simple adaptation of the screen module and different radii of curvatures of different slide tubes. 
     In some cases, each module surface section may include multiple pixels arranged one behind the other in the slide direction, the entirety of the module surface sections or the pixels being arranged thereon in a matrix or in a row resulting in the pixel matrix of the screen module. 
     As discussed above, it is possible on the one hand to achieve an image that extends over the entire circumference of the slide tube. On the other hand, it is possible to achieve an image over only a partial circumferential section of the slide tube by arranging at least one screen module, or alternatively multiple screen modules next to one another, in the circumferential direction. In the latter-mentioned design, the circumferential angle section that is not occupied with screen modules may have an at least partially, and preferably completely or nearly completely, reflective design, for example by integrating a reflective foil into the slide tube. In this way, a particularly cost-effective option is provided for producing an overall image that extends, at least predominantly, over the entire circumference, since the images of the partial section occupied by screen modules reflect on the reflective surface. 
     To ensure optimized heat dissipation of the pixels that are preferably formed from LEDs, it has proven to be particularly advantageous when the pixels arranged in a matrix, in particular LEDs, lie directly on the outer side of the slide tube that is acted on by water, at least in sections, on the inner side. In this way, the thermal conductivity of the water may be additionally utilized for the heat dissipation. 
     The water slide system may include wetting features, including at least one pump, for wetting the slide surface. Various options may be used for wetting the slide surface. In an aspect, a visible water stream, for example several millimeters in height, which flows along the slide tube may be generated on the slide surface. 
     Additionally or alternatively, it is possible, at least in sections, to generate merely a moisture film, for example by introducing moisture, e.g., water, via spray nozzles. This design may allow optimal cooling of screen modules situated, for example, in an upper tube section. 
     As discussed above, in one embodiment of the water slide system, the screen module may be designed as a stereoscopic display, and be actuatable and/or actuated for the simultaneous or time-delayed display of two different images, in particular differing with regard to the viewing angle of the displayed image contents, one for the left eye and another for the right eye of a user, in order to achieve a three-dimensional visual impression. Appropriate stereoscopically prepared image contents may be provided by an image source, such as a media server and/or a playback device. The slightly differing images, which in each case may be curved in two dimensions, possibly due to the preferred screen module curvature, are then combined in the brain to form an overall image for the perception of depth. 
     In this regard, stereoscopic viewing methods that provide the necessary separation or association of a left- and a right image for the eyes may be referred to as channel separation. As the result of appropriate design of the stereoscopic image information, optionally in conjunction with suitable channel separation features, for example polarized glasses and/or shutter glasses, it may be ensured that each eye is able to see only the image that is associated with it. One approach may include complete channel separation, in which the right image is completely invisible to the left eye, and vice versa. Another option, implementable within the scope of the water slide system of the present disclosure, which achieves a three-dimensional impression, may involve channel separation using circularly polarized light, the user in this case preferably wearing channel separation features in the form of polarized filter glasses. In the polarization process, images for the right eye and the left eye are preferably displayed at the same time, the channel separation features (polarized glasses) preferably allowing only every other line of the image to pass through, thus distributing half-images to both eyes. In an aspect within the scope of the water slide system of the present disclosure is the use of alternative shutter technology. In this approach, the images for the left eye and the right eye are displayed in succession, with control pulses preferably being sent to the channel separation features worn by the user, in particular, for example, shutter glasses. Shutter glasses mutually darken the installed “glass” in each case, in particular an LCD glass, to ensure that each eye sees only the image intended for it. It is also possible to implement a color anaglyphic approach, for example. In order to separate the two single images, preferably displayed at or near the same time, various color filters are used in the channel separation features (in particular, for example, red-green glasses). Alternative stereoscopic approaches are also usable, in particular those that do without additional channel separation features to be worn by the user. With these approaches, the screen module may have multiple pixel planes, in particular in the form of a so-called tensor display, which may be actuated with high refresh rates, such as at rates greater than 200 Hz, in particular 240 Hz or 360 Hz. 
     For some of the methods mentioned above, in particular the preferred shutter method and the preferred polarization method, it may be necessary for the user to wear channel separation features in an area in front of the eyes during the sliding operation. In the case of the shutter method, the channel separation features may be acted on by a control pulse that is synchronized with the display. For the special feature of a water slide system in which the user slides on a water film on the slide surface in the slide direction, it has proven to be advantageous when the channel separation features are securely and detachably fixable to the head of the user, preferably by tensioning with at least one elastic band and/or integrated into a helmet or a headband or the like. Notwithstanding, it is very advantageous when the channel separation features are designed in the manner of diving or swimming goggles, e.g., in such a way that the goggles are supported via sealing features, in particular an elastomeric material, on the head, about the area of the user&#39;s face, in order to avoid impairment of the image perception, and in particular to provide a three-dimensional effect between the eyes and a translucent surface (in particular eyeglasses) of the channel separation features. 
     In this regard, reference is made to the use of channel separation features, in particular in the form of glasses, preferably shutter glasses or polarized filter glasses, that are fixable, in particular tensionable, preferably on the head of the user, and/or use sealing features for water-tight contact on the body, in particular on the head of the user, during sliding on a water slide having at least one screen module, in particular during use of a water slide system designed according to aspects of the disclosure. 
     Regardless of whether the screen module of the water slide system is designed and actuated for displaying images with a two-dimensional effect or images with a stereoscopic or three-dimensional effect, according to one example, it is advantageous for the system to have a detector for detecting, at specific points or consecutively or continuously, a position and/or speed (in particular sliding speed) of the user, and for the screen module to be actuatable and/or actuated as a function of the position signal and/or speed signal of the detector, for example, in such a way that two-dimensional or stereoscopic image content, in each case in the form of a video, or alternatively, a stationary image or, in the case of a stereoscopic display, stationary images, which change as a function of the position signal and/or speed signal. In this way, particularly impressive effects may be achieved that are a function of the individual position of the person sliding along the water slide and/or of the person&#39;s speed. In one simple example implementation, the position may be detected using a photoelectric barrier, for example. It is also conceivable to arrange multiple photoelectric barriers (or other detection sensors) one behind the other in the slide direction in order to obtain position information and/or speed information that continues in a stepped manner. Alternatively, continuous position detection using suitable sensor features, for example a camera, or alternatively, multiple cameras, may be used. 
     The disclosure also sets forth a method for operating a water slide system designed according to various aspects of the disclosure. According to such aspects, it is provided that the at least one screen module is actuated in such a way that a moving image that is curved in the circumferential direction and is visible from the interior of the slide tube is displayed by the pixels of the screen module arranged in a matrix. The image may be provided by an image source, for example, a media server or a video player. The image may extend over multiple screen modules, thus resulting in an overall, in particular moving, image. 
     In an aspect of the method, the screen module or multiple screen modules may be supplied or actuated for displaying a moving (video) overall image, using stereoscopic images, to achieve a three-dimensional effect for the user. Depending on the technology used, during the sliding operation, the user may wear appropriate channel separation features (see the above discussion) or these may be provided to the user for use during sliding. It has been found to be particularly advantageous when these channel separation features are worn fixed in position on the body, e.g., may be detachably fixed to the body of the user, for example by tensioning using an elastomeric feature, such as an elastomeric band, or alternatively, the channel separation features may be equipped with sealing features for tight contact with the body, such as the head of the user, to prevent water from entering the area between the eyes, and the translucent surface of the channel separation features.

     DETAILED DESCRIPTION 
       FIG. 1  shows a section of a water slide system  1  that comprises a slide tube  2  made of translucent or transparent material. The slide tube  2 , in a manner known in the related art, may be made up of multiple tube modules  3  arranged one behind the other in a slide direction R, each tube module  3  in turn being mounted from multiple, in the present case a shown, two, shells  4 ,  5 , specifically, an upper shell  4  and a lower shell  5 . 
     The slide tube  2  in its interior forms a slide surface  6  that extends in the slide direction R. The slide surface  6  may be wetted with the aid of wetting features  7 . In the specific example embodiment shown, the wetting features  7  include a pump  8  that conveys a water stream in a circuit, the water being introduced in an upper slide area and collected in a lower slide area, and then provided once again to the water circuit. 
     It is apparent than a plurality of screen modules  10  may be situated on an outer side of the slide tube  2 , illustrated here with a circular cross section by way of example, the screen modules each having a plurality of pixels (not illustrated), in the form of high-performance LEDs. The LEDs may be arranged in columns and rows, e.g., in the form of a surface matrix, the pixels being individually actuatable in order to display images, such as moving images. 
     In an aspect, each screen module may have a minimum number of 15,876 LEDs (individual units) per square meter. 
     The screen modules  10  may optionally be curved only about an axis that extends in the slide direction R, e.g., in the circumferential direction of the slide tube, and have rows of pixels arranged in parallel to the slide direction R. The columns, oriented essentially perpendicularly thereto, follow the curvature of the outer side of the slide tube. 
     The screen modules  10  with their pixels may rest on the curved outer side. It is apparent that the screen modules  10  may have a shell-like design, and in each case may extend over a circumferential angle of greater than about 45°, and over at least about 0.5 m in each case in the slide direction R. 
     It is apparent from the arrangement according to  FIG. 1  that a plurality of screen modules  10 , six in each case as shown in this specific specific example embodiment, are arranged next to one another in the circumferential direction. Screen modules  10  are also arranged one behind the other in the slide direction R, so that by appropriately subdividing an original image, it is possible to divide it over the plurality of screen modules arranged in a matrix, so that all screen modules  10  or a group of these screen modules  10  display an overall image, which means that each of the screen modules shows an image detail. 
     In the specific example embodiment shown, in each case two adjacent screen modules  10  in the circumferential direction and in each case two adjacent modules in the slide direction are spaced apart from one another; one embodiment is also achievable in which the adjacent screen modules in the circumferential direction and/or the screen modules situated one behind the other in the slide direction R directly adjoin one another to thus allow a cohesive visual impression. 
     The shell-like design of the screen modules  10 , curved in the circumferential direction, is apparent in  FIG. 1 . This effect may be achieved in various ways. It is thus conceivable to use a curved LED carrier. Alternatively, as shown in  FIG. 3 , it is possible to use a screen module  10  that has multiple module surface sections  11   a  through  11   c,  in each case two adjacent module surface sections  11   a  through  11   c  spanning an angle with respect to one another. The pixels, such as LEDs, of each module surface section  11   a  through  11   c  in each case may span a (straight or noncurved) plane. In the simplest case, each section of the module surface sections may have only a single row of pixels extending in the slide direction R. However, each module surface section R may preferably have a plurality of such parallel rows extending in the slide direction R. 
     A design in which the module surface sections  11   a  through  11   c  are articulatedly connected to one another in order for the module surface sections to lie around the slide tube in the circumferential direction, essentially regardless of their diameter, is particularly advantageous in some implementations. Adaptation to different diameters is easily possible due to the articulated connection. 
     In  FIG. 1 , screen modules  10 , as mentioned, are arranged over the entire circumference of the slide tube  2 . An alternative embodiment, not shown, is conceivable in which only a partial circumferential section is provided with screen modules  10 . The slide tube may thereby have a reflective design in the remaining section in order to give the optical impression that more screen modules are provided than is actually the case. For example, it is conceivable to provide only the upper shell  4  or only the lower shell  5  with screen modules  10 , and to provide a reflective design, at least in sections, for the respective other shell. 
     It is apparent from the schematic illustration according to  FIG. 1  that the screen modules arranged in a matrix are actuated via actuating features  12 , which may include, for example, a video processor. The actuating features  12  may be supplied with an image signal, such as a video signal, from an image source  13 , such as a media server. 
       FIG. 2  shows a more detailed design of an example electronics system usable in accordance with aspects of the present disclosure. The image source  13 , which may be coupled to the actuating features  12  in a signal-conducting manner, may be located to the left in  FIG. 2 . The actuating features  12  may include a video processor unit  14  (video processor), which in turn is connected in a signal-conducting manner to a video splitter unit  15 , which may divide an overall image over four, by way of example, screen modules  10 . These screen modules  10  may be arranged next to one another in the circumferential direction or one behind the other in the slide direction.  FIG. 2  shows only the basic schematic design. Of course, the video splitter unit  15  may be designed in such a way that it supplies a curved matrix of screen modules  10 , as shown in  FIG. 1 , for example. 
     In some example implementations, the screen modules may be supplied or actuated with stereoscopic images via the actuating features  12  for achieving a three-dimensional effect for the user, such as when an overall image is achieved by appropriately actuating multiple screen modules via the video splitter unit  15 . 
     It may be advantageous in some implementations, when the detector (not illustrated) for detecting a position and/or a speed of the user is provided, and the detector is directly or indirectly connected to the actuating features  12  in a signal-conducting manner, for the actuating features  12  to adapt or change image content as a function of a detected position and/or speed. 
     Aspects of the present invention may be implemented using hardware, software, or a combination thereof and may be implemented in one or more computer systems or other processing systems. In an aspect of the present invention, features are directed toward one or more computer systems capable of carrying out the functionality described herein. An example of such a computer system  400  is shown in  FIG. 4 . 
     Computer system  400  includes one or more processors, such as processor  404  and a graphics processing unit  432 , which may correspond to the video processor unit  14 . The processor  404  is connected to a communication infrastructure  406  (e.g., a communications bus, cross-over bar, or network). Various software aspects are described in terms of this example computer system. After reading this description, it will become apparent to a person skilled in the relevant art(s) how to implement aspects of the invention using other computer systems and/or architectures. 
     Computer system  400  can include a display interface  402  that forwards graphics, text, and other data from the communication infrastructure  406  (from the graphics processing unit  432  or from a frame buffer (not shown)) for display on a display unit  430 . In an aspect, the display unit  430  may correspond to the screen module  10  or one or more of the the module surface sections  11   a, b, c.  Computer system  400  also includes a main memory  408 , preferably random access memory (RAM), and may also include a secondary memory  410 . The secondary memory  410  may include, for example, a hard disk drive  412  and/or a removable storage drive  414 , representing a floppy disk drive, a magnetic tape drive, an optical disk drive, a universal serial bus (USB) flash drive, etc. The removable storage drive  414  reads from and/or writes to a removable storage unit  418  in a well-known manner. Removable storage unit  418  represents a floppy disk, magnetic tape, optical disk, USB flash drive etc., which is read by and written to removable storage drive  414 . As will be appreciated, the removable storage unit  418  includes a computer usable storage medium having stored therein computer software and/or data. 
     Alternative aspects of the present invention may include secondary memory  410  and may include other similar devices for allowing computer programs or other instructions to be loaded into computer system  400 . Such devices may include, for example, a removable storage unit  422  and an interface  420 . Examples of such may include a program cartridge and cartridge interface (such as that found in video game devices), a removable memory chip (such as an erasable programmable read only memory (EPROM), or programmable read only memory (PROM)) and associated socket, and other removable storage units  422  and interfaces  420 , which allow software and data to be transferred from the removable storage unit  422  to computer system  400 . 
     Computer system  400  may also include a communications interface  424 . Communications interface  424  allows software and data to be transferred between computer system  400  and external devices. Examples of communications interface  424  may include a modem, a network interface (such as an Ethernet card), a communications port, a Personal Computer Memory Card International Association (PCMCIA) slot and card, etc. Software and data transferred via communications interface  424  are in the form of signals  428 , which may be electronic, electromagnetic, optical or other signals capable of being received by communications interface  424 . These signals  428  are provided to communications interface  424  via a communications path (e.g., channel)  426 . This path  426  carries signals  428  and may be implemented using wire or cable, fiber optics, a telephone line, a cellular link, a radio frequency (RF) link and/or other communications channels. In this document, the terms “computer program medium” and “computer usable medium” are used to refer generally to media such as a removable storage drive  414  and a hard disk installed in hard disk drive  412 . These computer program products provide software to the computer system  400 . Aspects of the present invention are directed to such computer program products. 
     Computer programs (also referred to as computer control logic) are stored in main memory  408  and/or secondary memory  410 . Computer programs may also be received via communications interface  424 . Such computer programs, when executed, enable the computer system  400  to perform the features in accordance with aspects of the present invention, as discussed herein. In particular, the computer programs, when executed, enable the processor  404  to perform the features in accordance with aspects of the present invention. For example, the processor  404  may perform features associated with the actuating features  12  described herein. Accordingly, such computer programs represent controllers of the computer system  400 . 
     In an aspect of the present invention where the invention is implemented using software, the software may be stored in a computer program product and loaded into computer system  400  using removable storage drive  414 , hard drive  412 , or communications interface  420 . The control logic (software), when executed by the processor  404 , causes the processor  404  to perform the functions described herein. In another aspect of the present invention, the system is implemented primarily in hardware using, for example, hardware components, such as application specific integrated circuits (ASICs). Implementation of the hardware state machine so as to perform the functions described herein will be apparent to persons skilled in the relevant art(s).
