Yoshimoto Cube

Açıklama

The Yoshimoto Cube is a polyhedral mechanical puzzle toy invented in 1971 by Japanese Naoki Yoshimoto (吉本直貴, Yoshimoto Naoki). The cube is made up of eight interconnected cubes and it is capable of folding and unfolding itself in a cyclic fashion. You can keep folding, or unfolding the cube, indefinitely. Once folded, the cube can be turned into two rhombic stellated dodecahedrons. Yoshimoto discovered that these two shapes could pieced together into a square when he was finding different ways he could split a cube equally in half. --------------------------------UPDATE------------------------------------ 6/13/2010 Yoshimoto Cube has just been blogged about on Makezine http://blog.makezine.com/archive/2010/06/3d-printableyoshimotocube.html 6/13/2010 As suggested by Michael Ragan, \"Now the n+1 step would be to design a printable mold for this component, so you could print the mold and cast, what is it--16 of these units that you need to make the cube?
