The Yoshimoto Cube: An Intriguing Geometrical Toy

is the transformation of two stellated rhombic dodecahedrons from a cube.

Naoki Yoshimoto (1971) discovered this cube when he was searching for a way to divide a cube equally in three-dimensional space. The result is a peculiar polyhedral dyad consisting of eight interconnected cubes that can be opened in multiple ways. The cube can be divided into two cubes and then transformed into two rhombuses, one silver the other gold with twelve faces each.

Here's a neat demonstration video, or you can see a line-art animation of the toy's action here at The World of Geometric Toy.

If you would like to make your own paper version then for the Origami enthusiast, download this file. Or if you prefer easier methods of getting a quicker model, then print and fold one of these.

Alternatively you may simply want to buy one !
