This is a pretty amazing folding transformation of a single-color 2-unit cube into a pair of stellated rhombic dodecahedra of different colors. Among its other interesting properties, the Yoshimoto Cube can actually be folded into a cube having the color of either star. You can buy the (fairly pricey) toy version pictured above from the Museum of Modern Art Store. It is also possible to make your own, from paper, by following the instructions in the video below. It is, reportedly, a very rewarding, if time-consuming, process. You can download the pattern here.
