ABSTRACT:
A movable mosaic formed by intersecting defined circular members each of which is rotatable about its center point and each of which comprises a plurality of discrete pieces formed by intersecting arcs of said circular members, said intersecting arcs having a radial dimension equal to the radial dimension of said circular members, each said plurality of discrete pieces including a first group of pieces whose arcuate surfaces are all convex and a second group of pieces whose arcuate surfaces are all concave.
Some of the pieces of each plurality of pieces will be common to at least two of said circles, said pieces being interchangeable between the circles by moving the pieces about the theoretical center points of said circles.
