Abstract: A flooring system as disclosed which includes a substructure placed on an earth surface, which supports a floor structure. The substructure is composed of a plurality of longitudinally-extending I-beams interconnected by longitudinally-extending styrofoam blocks. A floor structure is connected to the substructure, the floor structure including flooring pieces having a long side and a short side. The flooring pieces are connected to the substructure so that the long sides extend transversely to the length of the I-beams. In an alternative embodiment, the I-beams include a support and location leg for connecting the styrofoam blocks. According to a method of the invention, the substructure and floor structure are interlocked by the criss-cross pattern described.

Abstract: An apparatus and method for producing a multisided, multicolored display which includes an enclosure with a plurality of translucent light scattering sides, top and bottom. A plurality of light sources are positioned in a spaced apart relationship to radiate sufficiently to illuminate all of the light scattering sides. Each of the light sources is of a different color, and the radiation from each source overlaps radiation from the other sources on the light scattering sides. A plurality of symbols may be interposed between the light sources and the light scattering sides to create colored images. Each of the enclosures represents a module, wherein several discrete modules are structured in a matrix fashion, and the entire matrix comprises the display.
