Vertex-turning triangular dipyramid.
This is a vertex-turning triangular dipyramid that has 3 complanar axes of rotation. It ignores traditional axis systems since it allows 90°-moves. Each of the 6 faces has a star image on it (hence the name) and with only 3 possible moves the puzzle gets totally scrambled very easily.
It was said that this was the first puzzle with infinite number of states, because each move turns the inner circle by an irrational angle (~138.59°) and it will never reach the same orientation if you keep turning it in the same direction. In praxis this would not be a problem since the mechanism allows the circles to be turned independently from the rest of the puzzle.
If you're looking to buy, eBay is the one place you can find almost anything... if you're willing to wait for it, then pay the price!
