Each of the three bight box housings and the respective diffusers are formed with respective selectively-shaped peripheries. The first, second, and third light boxes are selectively positioned with respect to each other within a fixture housing that provides a dark background tot the backlit graphics, for the three selectively shaped peripheries and graphics to create a particular inverse cube illusion. The structural arrangement also provides the illusion that the statically displayed advertise lent graphic(s) is/are directed towards and follows the consumer as he/she approaches and then walks past the sign. The dark environment is provided by a housing of sufficient depth, having a dark surface that is preferably black. ## Claims ### Claim 1 A three-dimensional sign comprising: a first light box comprising: an enclosure; and a light transmitting panel positioned over an opening in said enclosure; said light transmitting panel comprising a first selectively-shaped periphery; a second light box comprising: an enclosure; and a light transmitting panel positioned over an opening in said enclosure of said second light box; said light transmitting panel of said second light box comprising a second selectively-shaped periphery; a third light box comprising: and enclosure; and a light transmitting panel positioned over an opening in said enclosure of said third light box; said light transmitting panel of said third light box comprising a third selectively-shaped periphery; a plurality of lights; wherein said light transmitting panel of said first light box, said light transmitting panel of said second light box, and said light transmitting panel of said third light box are selectively positioned with respect to each other for said first, second, and third selectively shaped peripheries to create an inverse cube illusion; and a respective graphic for each said light transmitting panel of said first, second, and third light boxes, each said graphic configured to be respectively visualized by a portion of said plurality of lights. ### Claim 2 (depends on 1) The three-dimensional sign according to claim 1, wherein said light transmitting panel of said first light box, said light transmitting panel of said second light box, and said light transmitting panel of said third light box being selectively positioned with respect to each other comprises positions wherein: a gap between said first light box and said second light box is configured to taper linearly; a gap between said first light box and said third light box is configured to taper linearly; and a cap between said second light box and said third light box is configured to taper linearly. ### Claim 3 (depends on 2) The three-dimensional sign according to claim 2, wherein each of said first, second, and third selectively shaped peripheries comprise a trapezoidal shape. ### Claim 4 (depends on 3) The three-dimensional sign according to claim 3, wherein said second selectively shaped periphery is a mirrored copy of said third selectively shaped periphery. ### Claim 5 (depends on 4) The three-dimensional sign according to claim 4, wherein each said respective graphic comprises an image distorted to respectively correspond to said trapezoidal shape of said first, second, and third selectively shaped peripheries. ### Claim 6 (depends on 1) The three-dimensional sign according to claim 1, wherein each said light transmitting panel comprises a light diffuser. ### Claim 7 (depends on 1) The three-dimensional sign according to claim 1, wherein each of said first, second, and third light boxes comprises a bezel configured to releasably secure said respective graphic to said respective light transmitting panel, to be backlit by said portion of said plurality of lights. ### Claim 8 (depends on 1) The three-dimensional sign according to claim 1, further comprising a selectively shaped housing configured to receive and support said selectively positioned first, second, and third light boxes therein. ### Claim 9 (depends on 8) The three-dimensional sign according to claim 8, wherein each of said light boxes comprises a light mixing chamber. ### Claim 10 (depends on 9) The three-dimensional sign according to claim 9, wherein an interior surface of said selectively shaped housing comprises a dark color; and wherein an exterior of each of said light boxes comprises a dark color. ### Claim 11 (depends on 10) The three-dimensional sign according to claim 10, wherein said interior surface of said selectively shaped housing is covered with black carpet. ### Claim 12 (depends on 10) The three-dimensional sign according to claim 10, wherein a rear portion of said selectively shaped housing comprises an enclosure for electronics. ### Claim 13 (depends on 8) The three-dimensional sign according to claim 8, further comprising a shaped bezel configured to mount a second graphic to said selectively shaped housing; and a second plurality of lights positioned to back-light said second graphic. ### Claim 14 (depends on 8) The three-dimensional sign according to claim 8, wherein said selectively shaped housing comprises a shape from the group of shapes consisting of: a dome shape; a cylindrical shape; a pyramid shape; a pyramid frustum shape; a cube shape; a dodecahedron shape; an octahedron shape; an icosahedron shape; and a polyhedron shape. ### Claim 15 A method of creating a three-dimensional inverse cube illusion sign comprising: forming a diffuser of a first light box with a first selectively-shaped periphery; forming a diffuser of a second light box with a second selectively-shaped periphery; forming a diffuser of a third light box with a third selectively-shaped periphery; positioning the diffuser of the first light box, the diffuser of the second light box, and the diffuser of the third light box for creating an inverse cube illusion using the respective selectively-shaped peripheries; positioning a plurality of lights for illuminating each diffuser of each of the first light box, the second light box, and the third light box; and positioning a respective graphical image for contacting the diffuser of the first light box, the diffuser of the second light box, and the diffuser of the third light box; and backlighting of each respective graphical image.
