Forget Rubik's, I Want A Yoshimoto Cube
A Yoshimoto Cube is actually two separate cubes nested together. The technical terminology for the change is "the transformation of two stellated rhombic dodecahedrons from a cube". Honestly, I just like listening to this guy's voice. It's soothing, like a homicidal maniac's.
Thanks to OJ's Mom, who once transformed a stellated cylinder in his pants into a dodickahardon IN YO FACE!
