When making up rotational puzzles, it must be difficult to think up new ideas to basically the same shape. Oskar van Deventer has made a rotational puzzle that might have the same shape but definitely does not move the same way. To make it harder he has made two variations of the same kind of concept. Once again Oskar`s designs are thought provoking and minding bending.
