ABSTRACT:
An educational toy and method for demonstrating characteristics of a latticework of spacepoints including demonstrating (a) the commonality of latticework between tetrahedron configuration latticework and octahedron configuration latticework, (b) that octahedron latticework merges with tetrahedron latticework, (c) the 13-plane structure of the common latticework, (d) how simultaneous twinning in more than one of the 13 planes can form multitudes of combinations of domains of tetrahedrons and octahedrons, and (e) the altering of latticework by appropriately selecting the dimensions of structure members that define spacepoints in the latticework. Preferably, the structure members are similarly dimensioned and oriented ellipsoidal elements which are gravity stacked and optionally connectable and wherein the centerpoint of each ellipsoidal element represents a spacepoint in the latticework. With ellipsoidal elements, the latticework structure is determined by the relative lengths of the three orthogonal axes of symmetry of the ellipsoidal elements when the common axis and the location of either orientation mark are known.
