ABSTRACT:
Interlocking plastic blocks, trademarked as PIXELBLOCKS, are configured to serve as basic pixels, i.e. picture elements, in the creation of a variety of two- and three-dimensional graphic artifacts. The pixel blocks can be made in various equilateral polygonal cross-sectional shapes of designated length, typically embodied in an equilateral cube shape. All side facets in the outline of cross-sectional shape, e.g. four facets of the cube, are made identical, each facet configured with a tongue alongside a groove in a symmetrical complementary configuration such that adjacent blocks can be interlocked together to form one- and two-dimensional arrays; thus pixel blocks of uniform depth front-to-back can form two-dimensional artifacts. A 3D embodiment includes posts and post holes for Z axis attachment to form multi-layer three-dimensional artifacts. By utilizing the blocks in a variety of visual properties such as color and light transmission, quantities of pixel blocks may be interlocked together to form pictures, graphics patterns, beams and other artifacts, optionally enhanced by electric lighting effects for which the pixel blocks may be specially configured.
