Tony Fisher's transformation of a 5x5x5 Rubik's Wahn. He was going to make a basic Cuboctahedron but started cutting in the wrong place. He discovered by continuing that this shape was possible. The reason for the strange curves is that the cuts are so deep they actually go into the mechanism. Any further and the whole puzzle would fall apart. Only one exists.
