ABSTRACT:
Crescent-shaped, polygonal tiles useful for covering walls, floors, ceilings, streets or paths and for producing toys, games and structures. The tiles each have a substantially convex outer edge, a substantially concave inner edge, and at least seven sides forming the edges. In some instances, these sides are straight and of equal length, and in other instances they are not straight but enclose the same area as enclosed by the straight sides of equal length. The tiles, either by themselves or in combination with others, interconnect to fill a plane. Either by themselves or in combination with others, the tiles form mosaics with periodic or non-periodic patterns.
