     FIELD OF THE INVENTION 
     The present invention is generally in the field of articles of manufacture, and particularly clothing and footwear, which includes a lighted effect, an example of which is created using a LED lighting module. 
     BACKGROUND OF THE INVENTION 
     Lighting systems have been used before both with footwear and with clothing, examples of which are set forth in my prior U.S. Pat. Nos. 5,649,755 and 7,347,577, the disclosures of which are specifically incorporated herein by reference. If a lighting module is to be used with clothing, it must not only be durable, but it must also be washable. One way this has been done before is to include both the lighting module and the lights within a pouch that is waterproof, such as is taught in U.S. Pat. No. 7,857,477. However, such a pouch has a number of limitations, and the present invention therefore seeks to improve such prior devices. 
     SUMMARY OF THE INVENTION 
     The present invention is generally directed to creating a sparkling viewing effect in which a light material viewing effect attributable to a given LED is seen to move about a light effect material as an electronic assembly moves within a chamber when the given LED is emitting light. The sparkling viewing effect can be synchronized with a sound effect, and multiple devices can be triggered to create synchronized light material viewing effects by a broadcast signal. 
     Accordingly, it is a primary object of the present invention to provide an article of manufacture with an improved light material viewing effect. 
     This and further objects and advantages will be apparent to those skilled in the art in connection with the drawings and the detailed description of the invention set forth below.

     DETAILED DESCRIPTION OF THE INVENTION 
     The concept of use of a light effect material is disclosed and discussed in U.S. Pat. Nos. 9,445,641, 9,506,643, 9,557,049 and 9,706,803. Light effect material is maintained at an acceptable distance from a light source using one or more LEDs behind it relative to a viewer so as to create a visually interesting effect for the viewer viewing the light source through the light effect material. More particularly, the general effect of the light effect material is that the light effect viewed by the viewer is over a larger viewing area than what the viewer sees along the exact same viewing path with the light effect material removed from the viewing path, and the light effect is more visually interesting. The light effect material may be incorporated into a garment inside of an application or patch, and multiple layers of the light effect material may be used. 
     A light effect material creates a visually interesting effect in which light from an LED behind such material, relative to a viewer on the other side of the material, will see a dispersed pattern of light created by the material, when the light effect material is located at an acceptable distance between a viewer and one or more LEDs. A light effect material must be sufficiently sheer or transparent to allow light from an LED to pass through it and be seen by a viewer&#39;s eye, but it must also have a structure that allows some of the light from the LED to reflect along its structural components to disperse light and create a noticeable optical effect. It is for this reason that a light effect material, if it is located directly adjacent to an LED, will have little or no noticeable optical effect, whereas the same will be true if it is located too far away from an LED. In choosing a material with dispersive elements, it is especially desirable to choose a clear or white material with prismatic properties instead of a colored material when the material is being used with multi-colored LEDs, so that the color of the material with reflective elements does not interfere with the color of the LEDs. In connection with such a light effect material, it is important that the reflective and/or refractive elements are sufficiently small so that they give the appearance of creating multiple points of light for each LED, rather than simply acting as a prism or a large multifaceted lens. Also, it is especially useful if multiple LEDs are spaced apart from light effect material so that multiple LEDs, especially of different colors, can overlap each other to create blended light effects. 
       FIG. 1  illustrates an LED spaced apart from a light effect material (the LED can be a bi-pin LED, an axial lead LED or a surface mount LED). The LED has a light emitting die which rests on a base and is covered with a dome. The light emitting die of the LED emits light and, in one especially preferred embodiment, the light effect material has active elements which create the light effect that are roughly the size, or within several orders of size magnitude, as that of the width of the semiconductor die used in an LED. Also, although the distance Y between the LED and the light effect material can vary, it has been disclosed that a distance of around 10 to 2000 times that of the LED (Z in  FIG. 1 ) is effective where the light effect material has a thickness X which is roughly the same as Z. 
     An example of a material that can function as a light effect material, which is an especially preferred embodiment, is a material with microscopic reflective and/or refractive elements on its outer surface relative to an LED (meaning that rays of light emitted from the LED will pass into an inner surface of the light effect material and then exit the light effect material at its outer surface and then continue on to a viewer) that serve to disperse light. One example of such a material is illustrated in  FIGS. 3 and 8 . In this example the light effect material is created as a surface layer of a larger piece of material, such as PVC or polyurethane, and the microscopic reflective and/or refractive elements can be machined or cut into the sheet or created by a molding process. The reflective and/or refractive elements in this example have a pyramidal shape (see  FIG. 3 ) when viewed up close, but alternating squares of such shapes are configured at different angles as is illustrated in  FIG. 8  in which the triangular lines represent the base lines of the pyramidal shapes illustrated in  FIG. 3  and the top pyramidal points of  FIG. 3  would be located in the centers of the triangles shown in  FIG. 8  (except that such points and the angled surfaces converging at such points are not shown so that the size of the pyramidal base lines can be accurately set forth). Note also that the elements extend away from the surface relative to the location of one or more LEDs, as is illustrated in  FIG. 4 . 
     In connection with the light effect material illustrated in  FIGS. 3 and 8 , alternating squares of repeating patterns, each different from an adjacent square, help create a mosaic like surface having microscopic surfaces. Due to the differences in the microscopic elements of such light effect material, some squares of microscopic surfaces may create a light effect that can be viewed by a viewer, while others will not, which is conceptually illustrated in  FIG. 9  as a simple alternating pattern of squares that do and not create a light effect. (In connection with  FIG. 9 , it is worth noting that the physical size of the LED semiconductor die is actually roughly the same as a single base line of one of the pyramids of one of the squares illustrated by  FIG. 8 , but the LED, for purposes of illustration only, is not drawn to such scale in  FIG. 9 ). However, the alternating patterns can be designed in more complex patterns to create desired effects, examples of which are illustrated in  FIGS. 5 and 7 . 
     In  FIG. 5 , a viewer at a certain distance views a circle of lights, such as twelve, about a central, dimmer light, all of which are produced by a single LED. This effect is conceptually illustrated in  FIG. 7 , albeit with a different number of lights, in which the squares without any cross hatching represent squares of the light effect material having microscopic elements that create a viewable effect whereas the squares with cross hatching do not create a viewable effect (at least at the particular distance from which the material is being viewed by a viewer). 
     While  FIG. 8  illustrates a light effect material in which microscopic elements are arranged in a mosaic pattern that can be used to achieve recognizable patterns, microscopic elements can also be arranged randomly, or nearly randomly, to achieve a different light effect, such as that which is illustrated in  FIG. 6 . 
     Another example of material that can function as a light effect material according to the present invention is a shiny filament fabric material, which may or may not be sheer, in which light appears to travel along structural fabric components to disperse light and create an optical effect. In such fabrics, the further the fabric is away from the light source, the greater the optical effect that is observable, up to a limit in which the effect is lost because the distance is too great. Such a light effect material can be used on its own or affixed to another layer of material, such as, for example, transparent PVC, which can then be incorporated into the structure of an article of manufacture, one example of which is footwear. 
       FIG. 10  illustrates a light effect material that uses a woven fabric material in which the shiny filaments of the woven fabric help create a light effect. As illustrated in  FIG. 10 , an LED is located behind the woven fabric light effect material and a viewer sees a light effect in which the linear fabric material is illuminated within a certain distance emanating away from a central point of the LED behind the light effect material relative to a viewer. The result, in this instance, is a design in which the light from a single LED is greatly enhanced to give a light effect more equivalent to that of several LEDs. 
     Multiple light effect materials can be layered on top of each other to create a hybrid light effect. Thus, for example, two sheets of light effect material, such as are illustrated in  FIGS. 2 and 7 , can be layered on top of each other—in this example, the thickness of the light effect material, between its inner surface and its outer surface where the dispersive elements are located, serves as a transparent space between the two layers of dispersive elements located on the outer surface of the two sheets of light effect material, thus enhancing the hybrid light effect. 
     Accordingly, a variety of different light effect materials can be used to create different light effects. Common to all such materials is use of very small, or microscopic, elements which create visible light effects in which an LED is no longer viewed as simply a single point source of light, but as something more akin to that which is produced by additional LEDs. 
     One or more sheets of light effect material can be used as an outer surface of a lighting element, or they can be protected by an outer transparent layer. It is especially preferred, if an outer protective transparent layer is used, that the outer surface of a light effect material located next to the outer transparent layer material be sealed so that liquid, which may contain soap and the like, is not allowed to reach the dispersive elements of the outer surface of the light effect material during a wash cycle so that no residue is trapped or deposited on the dispersive elements that might diminish their light dispersive effect. 
     When a lighting unit is being manufactured, the light effect material and spacing mechanism can be thought of as half the unit, the other half being the LEDs and electronics used to power the LEDs, such as a power source (which can be one or more batteries), a control device powered by the power source for controlling electric current provided to the LEDs (which may have a light sequencer or timer or other electronics, all of which can be contained on a PCB), a switch (such as a motion detector switch, an example of which is U.S. Pat. No. 9,396,887) and one or more electrical connectors (such as conductive wires) to connect the LEDs to the control device. With such a construction, both of said halves, namely the lighting half and the electronics half, can be separated, if desired, or combined into a single unit and the LEDs can be mounted on a PCB with the other electronics, depending upon designer choice. 
     U.S. Pat. Nos. 9,863,615 and 10,145,546 disclose a lighting unit can be removably inserted into a pocket which can be made of light effect material. 
     In accordance with the disclosure of U.S. Pat. No. 9,863,615, a self-contained insertion assembly  400  is manufactured which contains all of the electronics and LEDs in a single assembled unit which can include (or not) a light effect material and is removably inserted into a pocket prepared in a garment or other item of manufacture. The pocket is designed to keep the unit correctly orientated if orientation is required for a switch while also allowing for easy removal and or replacement of one or more units and/or sheets of light effect material while still also allowing for a light effect to be visible outside of the pocket. 
     As illustrated in  FIG. 11 , a battery  6  is directly mounted to a PCB  8  which also contains one or more LEDs  5 , electronics  2  and a switch  3  (which may either be mounted directly to the surface of PCB  8  to which the other components are mounted or, if desired, mounted in a recess or hole formed in PCB  8  to reduce the elevation profile of switch  3 ). LEDs  5 , electronics  2  and battery  3  are mounted to the same surface of PCB  8  and the LEDs are arranged so that a distance D between them and other components such as battery  6  and switch  3  minimizes light emitted from the LEDs coming into direct contact with the elevational profile of such components which will interfere with the pattern of light emitted due to shadow effects. If an on/off switch  4  is included, it can be connected by wires  20  to the same surface of PCB  8  to which LEDs  5  are mounted, as is illustrated in  FIG. 11 . The assembly described so far (but not on/off switch  4 ), once assembled, is encased in a clear potting material P to create an assembly  410 . It is especially desirable that potting material P is used to create the transparent space with a preselected distance needed between LEDs  5  and light effect material  50  so as to create a light material viewing effect. 
     Assembly  410 , in an especially preferred embodiment, is combined with light effect material  50  and two pieces of plastic material  401  and  402  to create a further assembly  400 . It is especially preferred that plastic material  402  is self-sealing to plastic material  401  and allows for attachment  410  to be stuck to it. In an alternative embodiment, plastic material  401  may itself be a light effect material  50 , thus removing the need for three sheets of material illustrated in  FIG. 12 . In another alternative embodiment, assembly  410  may be included within another structure, such as a clear envelope or the like, and then attached to light effect material  50  (e.g., by using clear adhesive or tape or the like), and then assembly  410  or assembly  400  and (any additional structure) and one or more sheets of light effect material  50  (all of which will hereinafter collectively be referred to in any combination or sub-combination, for ease of reference, as removable assembly  500 ) may be removably inserted into a pocket  501  designed for receiving removable assembly  500 , an example of which is shown in  FIG. 13 . 
     It is desirable for pocket  501  to have some type of reversible closing mechanism  503  to retain removable assembly  500  within it, and such closure mechanism can take any number of forms, examples of which include, but are not limited to, a zipper, a snap, a button, or a hook and loop fastener, which may or may not use a separate flap of material  502  which partially covers pocket  501  and is used in connection with reversible closing mechanism  503 . In an especially preferred embodiment, pocket  501  has a clear portion  505 , a border  506  and some attachment mechanism  507  (e.g., stitching or heat seal) for attaching pocket  501  to a surface of a garment (such as a piece of clothing or shoe) or other article of manufacture (e.g., a backpack, toy or something else). Alternatively, pocket  501  itself might be attached to a surface, such as that of a cell phone, by an adhesive layer or the like. It is worth noting that clear portion  505  may include its own artwork or be comprised of light effect material  50 , or have light effect material  50  attached to it, in alternative embodiments, and may also be a sheer material, rather than a clear material. 
     Use of multiple pockets  501  on a single surface or garment, especially when combined with multiple sheets of light effect material  50  that are easily combined or removed from a single pocket, and the possibility of differing removable assemblies  500  (which might have different numbers of LEDs, or colors of LEDs, or patterns of lighting) create the possibility of a great many customizable variations of light effect viewable on the single surface or garment. Also, multiple removable assemblies  500  and differing sheets of light effect material  50  might be sold in a kit for use in customizing a given garment or for use in replacing a removable assembly  500  in a given pocket or garment. Indeed, a garment with a specially designed pocket  501  might be sold or shipped separate from a removable assembly  500  designed for use in such garment. 
     In accordance with the disclosure of U.S. Pat. No. 10,145,546, a compact, inexpensive lighting assembly  600 , illustrated in  FIGS. 14-16 , can be manufactured which is useful when combined with light effect material  50 . 
     In an especially preferred embodiment, battery  6  is mounted to an underneath side  8 U of PCB  8  through use of battery mount  6 M while other electronic components are mounted on top side  8 T of PCB  8  to produce a very compact electronic assembly  601 . (Note that battery  6  can also be mounted on top side  8 T if size is not an issue and a larger PCB is acceptable for a given application.) The electronic components mounted on top side  8 T include multiple LEDs  5 , electronics  2  and an on/off switch  4  (as well as a motion switch, if desired). PCB  8  can be a flexible circuit or use a rigid circuit board. 
     After electronic assembly  601  is assembled it is inserted into a first plastic piece  602  with a cavity  602 C and bottom housing  602 B so that top side  8 T is more proximate to bottom housing  602 B than underneath side  8 U and then a second plastic piece  603  is placed over the first plastic piece  602  and sealed to form lighting assembly  600  which has a watertight seal which protects electronic assembly  601  which is now sealed between plastic pieces  602  and  603 . The watertight seal may be made by any number of conventional sealing means, examples of which include a shrink wrap step, a heat seal, a sonic weld, a clamp, glue or some other sealing means, and it is desirable that any edges be rounded and/or softened so as to avoid sharp edges. It is important to note that it is especially desirable that depth  602 D of cavity  602 C be sufficient so that bottom plastic housing  602 B is spaced apart from contact point  4 C of on/off switch  4  so that applying pressure to bottom plastic housing  602 B, such as by finger activation, causes bottom plastic housing  602 B to bend down until contact is made with contact point  4 C for either turning switch  4  on or off or for activating changes in different operational modes of LEDs, examples of which include a chase sequence, simultaneous blinking or all on at once. Also, depth  602 D provides space between LEDs  5  and any light effect material  50  so as to create a light material viewing effect. 
     While it is possible that light effect material  50  can be used for bottom plastic housing  602 B, it need not be, and light effect material  50  can be placed on or apart from bottom plastic housing  602 B so as to create a lighting unit removably insertable within a pocket, or it can also be incorporated into an article of manufacture, such as a piece of jewelry, a novelty item or as a decorative patch. 
     First and second plastic pieces  602  and  603  can be made of any suitable material, such as materials in common use for clam shell packaging today, which means that production of lighting assembly  600  can be automated, and then lighting assembly  600  can be incorporated into a suitable article of manufacture, depending upon its intended use. It is especially desirable that plastic piece  602  be clear so as to allow light emitted from LEDs  5  to pass through it. 
     Lighting assembly  600  can be used to replace assembly  410 , as previously described, or it can be used to replace assembly  400 , as also previously described. It can be used to create removable assembly for insertion into a pocket, or it can be incorporated into an article of manufacture, such as a shoe, where it may or may not be replaceable, depending upon designer choice. And, because of the compact size in which a multi-LED lighting unit  600  can be produced, multiple lighting units  600  can be used in a given application, either with or without light effect material  50 ; for example, multiple lighting units  600  can be used in a given insert, with light effect material, for insertion into a pocket, so that the lighting units  600  can create different light material viewing effects designed to complement or enhance graphics included with the pocket insert or to be lighted by the pocket insert. 
     A pocket insert (or a similar article of manufacture which may also be secured to another article of manufacture by any suitable means, either permanently or removably), can include electronics  2  which include a controller, a motion activated switch and wireless connectivity, such as Bluetooth, so that any lighting unit, such as what might be placed in a pocket, can be remotely controlled by a portable personal electronic device, such as, for example, a cellphone, tablet, or computer. (Thus, it should be noted that electronics  2  is not necessarily a singular device as depicted in  FIGS. 14-16 , although it may be, depending upon desired electronics, designer choice and manufacturing considerations, an example of which might include use of an ASIC chip.) Furthermore, sound can be included in electronics  2  via one or more sound devices, and one or more controllers can coordinate sound and light material viewing effects, either with preprogrammed selections, or through wireless control via a portable personal electronic device, which might allow a user to coordinate preselected patterns via the means for providing wireless connectivity or control activation of noise device(s) and LEDs according to one or more user inputs transmitted from a portable personal electronic device. 
     U.S. Pat. No. 10,364,973 discloses a metalized layer can be added between a light effect material and the viewer so that components creating a light material viewing effect are masked by the metalized layer when the light material viewing effect is not activated whereas the metalized layer enhances a visual design (such as artwork) when the light material viewing effect is activated. 
     It has been previously disclosed that what I shall refer to as a “metalized layer” can be added outside of a light effect material relative to a ray path drawn from an LED and this metalized layer will create highly desirable visual effects. When the LED is not energized and producing light, the metalized layer will give the appearance of a metalized layer of material, thus hiding what is found underneath it; however, when the LED is energized, the light effect will still be created and visible on the metalized layer. To create this special visual effect, the metalized layer needs to contain a light deposition of metal, but not be opaque. The metalized layer can be its own layer of material attached to the light effect material or another layer located between the light effect material and the metalized layer. It is also contemplated that the metalized layer might be deposited on the outer surface of the light effect material (relative to an LED). 
     Due to the visual effect created by the metalized layer when no light is creating a light effect, the metalized layer can be incorporated into an aesthetic design of an article of manufacture (e.g., but not limited to, clothing or shoes), one example of which might be to give the appearance of a metalized button, bar, square or other shape, so that the visible portion of an article of manufacture capable of creating a light effect is the visual image of the metalized layer when no light effect is being created. Thus, for example, a metalized layer  75  can be added to self-contained insertion assembly  400  previously described in  FIG. 12  as is illustrated in  FIG. 17 . It should be noted that a metalized layer  75  can be used in any previous embodiment already described which creates a light effect. 
     Visual designs can also be created on the metalized layer (or on a light effect material or outer surface when it is not being used with a metalized layer) which take advantage of the light effect to highlight a portion of the aesthetic design or the light effect (visible either with or without a metalized layer) may be incorporated into a larger design of an article of manufacture, examples of which are illustrated in  FIGS. 18 and 19 . 
       FIGS. 18 and 19  also illustrate how a light effect material and/or metalized layer can be incorporated into the design of an article of manufacture, such as a garment or shoe, as a pocket-like receptacle for receiving an electronic assembly used to create a light effect. In the example illustrated in  FIGS. 18 and 19 , an article of manufacture, such as shirt  700 , contains artwork  701  which includes a portion of artwork  702  which incorporates an active light effect into its design; the additional artwork can be incorporated in a light effect material or metalized layer, either of which themselves could be incorporated into the article of manufacture, such as shown in  FIGS. 18 and 19  as pocket  703 . Once the light effect is activated, as illustrated in  FIG. 19  as  705 , the light effect now adds an electronic effect to artwork  701  (and, if present,  702 ). In  FIGS. 18 and 19 , a self-contained insertion assembly  400  can be added inside of pocket  703  and this assembly can have extended sides of material (see  FIG. 13 ) so that it fits the pocket and makes it large enough so that it will not represent a choking hazard to young children. The pocket, as already discussed earlier, can have a closure mechanism to hold the self-contained insertion assembly  400  inside of it. Another advantage of such a design is ease of manufacturing assembly, given that the pocket can be made directly in the article of manufacture and then a self-contained insertion assembly  400  can easily be inserted into the pocket (and, if desired, closed within the same); further, such a design facilitates the use of multiple self-contained insertion assemblies, and multiple pockets create opportunities for personal customization. 
     Accordingly, the addition of a metalized layer greatly increases designer choice and aesthetic designs that can be created with a light effect material. The metalized layer can cover all of the light effect material or less than of the light effect material, depending upon designer choice. 
     In accordance with the disclosure of U.S. Pub. No. 2019-0316767 A1, light effect material may be incorporated into a flap which extends down over all, or substantially all, of the length of a pocket (rather than just being a top flap, as is illustrated in  FIG. 13 ) while a lighting module is held within the pocket, the spacing between the flap and the lighting module held within the pocket creating the needed distance, or additional distance, between the light source and the light effect material so as to create or accentuate a light material effect. Of course, if the flap also contains a transparent spacing material (e.g., bubble wrap or the like) the transparent spacing material, plus the natural spacing between the flap and the pocket, can be used in creating a light material effect. Also, if the flap is not secured, and it is allowed to move around during physical activity, such as when a person wearing a garment is physically active, movement of the flap will cause the light material effect to vary, due to the varying distance between the light effect material on the flap and the lighting module held within the pocket. 
     The present application builds upon prior disclosures by recognizing that one or more light assemblies can be located within a chamber in which they can move about so as to create what I will call a sparkling viewing effect in which the light material viewing effect attributable to any given LED is seen to move about light effect material as its electronic assembly moves within the chamber when such given LED is emitting light. 
     A chamber  710  of the present invention can have one or more viewing surfaces which may be planar, curved or a complex shape. One example of this concept is illustrated in  FIG. 22  in which an article of manufacture  700  has a shell  702  (see  FIG. 23 ) attached to handle  701 . Note that shell  702  need not be circular and can, for the sake of illustration, be another shape, such as a cone, rectangle or cylinder, or have a non-geometric shape, such as a replica of an object, a few examples of which are a head, body, figurine, car, airplane and the like; alternatively, a simpler shape can be used for the shell and an outer artistic shape or shell can then be attached to the inner shell. At least a portion of shell  702  (if not the entire shell) is transparent so that light emitted from within it is visible outside the shell, and at least a portion of such transparency (and, in an especially preferred embodiment, all of such transparency) is configured with one or more light effect materials and, optionally, a metalized layer, to create one or more light material viewing effects (as is taught and discussed in my earlier applications), and one of ordinary skill in the art will recognize that varying between transparency and not in shell  702 , and the type of light effect material with or without a metalized layer, creates a great deal of designer choice useful in creating ornamental light viewing effects. 
     Chamber  710  of the present invention is configured to hold one or more light assemblies (a non-limiting example of which is previously described assembly  400 ) which can move about within chamber  710 . Such movement causes light emitted from a given LED on a given light assembly to be emitted from different locations of shell  710 . If one or more light assemblies are sealed within the chamber during manufacture, they can be activated when there is motion of the chamber (e.g., by a motion detector device or circuit contained within electronics of, or in communication with, the one or more light assemblies) or by a signal originating from outside of the chamber by a wireless communication device. If a wireless communication device, such as a portable personal electronic device, is used to activate LEDs contained within the chamber, the same device can be used to communicate with a controller to select or alternate a pattern of which LED lights are activated at the same or different intervals of time, as well as to activate sound (e.g., musical tunes) if such capability is included in the electronics of a given light assembly; in one such especially preferred embodiment, the sequencing of LEDs is synchronized with music to create a combined effect, such as a simulated fireworks display synchronized to music typically displayed at a fireworks display in the United States on the Fourth of July. Chamber  710 , in an especially preferred embodiment, contains air, although it can also contain a fluid, including a viscous fluid, to create a lava lamp-like effect. In alternative preferred embodiments of the present invention, one or more light assemblies can be removably inserted into chamber  710  by a consumer or person using article of manufacture  700  through a reversible closing mechanism, a non-limiting example of which is illustrated in  FIG. 23  as a movable flap  703  secured by the closure mechanism of latch  704 , and such assemblies can be configured with their own on/off switches. It is worth noting that multiple articles of manufacture  700  can be designed so that they are synchronized to be used simultaneously at an event, such as a concert, sporting event, fireworks display and the like, and they can all display light and/or sound effects triggered simultaneously (e.g., in a sporting event, they can all exhibit a certain preselected pattern in the event of a scoring event) when they are triggered by a wireless communication broadcast to all of the articles of manufacture simultaneously, and that other articles of manufacture which do not contain a chamber  710 , such as other items already described, one example of which is shirt  700  illustrated in  FIGS. 18 and 19 , can also have light effects and/or sound effects triggered by the same broadcast communication. 
     If chamber  710  is configured so that it is viewable from a variety of different viewing planes, such as spherical chamber  710  shown in  FIG. 22 , as opposed to having a more limited planar viewing plane as shown in  FIG. 25 , it is especially desirable to use a lighting assembly which has LEDs located in different, or opposing, viewing planes. One way this can be done for opposing viewing planes is to simply connect two light assemblies, such as  400 , back-to-back, as is shown in  FIG. 23 ; alternatively, a lighting assembly can be designed with multiple PCBs, or with LEDs located on a front and back side of a PCB. 
     While the present invention has been described with reference to a chamber  710  configured to hold one or more light assemblies, wired LEDs can also be allowed to move with chamber  710  to create a sparkle effect, and  FIG. 24  illustrates one embodiment of such an article of manufacture in which an LED is simply connected to positive and negative wires,  5 P and  5 N, respectively, which are then connected to electronics  850  which can be configured within a suitable location of article of manufacture  700 , such as handle  701 . Electronics  850  can include a power source or, in a less preferred embodiment, be wired to a power source. Of course, multiple LEDs can be connected to one pair of wires, and multiple wires of one or more LEDs can be located within chamber  710 . 
     Although the foregoing detailed description is illustrative of preferred embodiments of the present invention, it is to be understood that additional embodiments thereof will be obvious to those skilled in the art. Further modifications are also possible in alternative embodiments without departing from the inventive concepts already described. 
     Accordingly, it will be readily apparent to those skilled in the art that still further changes and modifications in the actual concepts described herein can readily be made without departing from the spirit and scope of the disclosed inventions.
