Soma cube, Frameworks, Zome, and more - Math Cats
Frameworks and Zome are both geometric construction sets made of plastic pieces which snap together.
Piet Hein, desner of the Soma Cube - Froebel Web
Frameworks' plastic pieces are polygons whose edges snap together. Struts come in different lengths and colors; each color has a different polygon on its ends.

It is a beautiful freak of nature that the seven simplest irregular combinations of cubes can form a cube again. If we consider the "a" and "b" pieces (a chiral pair) to be interchangeable in reflection, there are exactly half as many solutions as shown for each of the puzzles below. The puzzle contains one piece from each of the solid polyominoes of orders 2 through 7 (i.e one solid domino, ..., one solid heptomino), for a total of 27 unit cubes.Soma Cube - JesWeb - jeux de société
