My friend Indra Samala just brought to me a brand new piece of !!i!. Actually it was a twisty puzzle. It is called Master Pyramorphix. It looks like pyramid in shape, but it's a little bit rounded. But, unlike the Rubik's Cube, to play it, you don't twist the faces. Instead, we twist the edges! We can deform the puzzle into many kinds of abstract, or even irregular shapes, hence the name 'pyraMORPHix'.
Actually, if you examine the group of pieces that twists, it's similar to Rubik's cube in structure and in the solution. The six "edge pieces" are actually the center pieces, and they are fixed relative to each other.
