Claim:
A kit comprising two mating elements for assembling a ball, each mating element comprising: an exterior surface bounded by an edge; an annular surface joined to said exterior surface at said edge including two opposing, aligned recesses oriented radially inward from said edge; a well abutting a portion of said annular surface and one of the recesses, the well extending toward said exterior surface; and an alignment guide abutting a portion of said annular surface and the other of said recesses, said alignment guide extending away from said exterior surface and having a hole therethrough in alignment with said aligned recesses; wherein said mating elements are substantially identical in shape and size and are matable with each other to form a ball, with said edges contacting each other, said annular surfaces contacting each other, and each alignment guide extending into the well of the other mating element, thereby positioning the aligned recesses and the holes to define a channel through the mated elements, wherein the channel is sized to contain a light source.
