Soma cube Soma cube The Soma cube is a solid dissection puzzle invented by Piet Hein in 1933 during a lecture on quantum mechanics conducted by Werner Heisenberg. Its name is alleged to be derived from the fictitious drug "soma" consumed as a pastime by the establishment in Aldous Huxley's dystopic novel "Brave New World". Seven pieces made out of unit cubes must be assembled into a 3×3×3 cube. The pieces can also be used to make a variety of other 3D shapes. The pieces of the Soma cube consist of all possible combinations of three or four unit cubes, joined at
Void Cube retained by a trio of short circular flanges at the ends of the interior sliding pieces. When a face is rotated, those short flanges temporarily retain edge cubies, particularly when the face is rotated about 1/8 of a turn (roughly 45 degrees). As well, the corner cubies are temporarily retained by the curved flanges on the neighboring square pieces. During a rotation, flanges "change roles" as cubies travel along their circular paths. Void Cube The Void Cube is a 3-D mechanical puzzle similar to a Rubik's Cube, with the notable difference being that the center pieces are missing, which causes
