Puzzle Details

5 rotational circles are arranged in the 4 corners and the center of a square. Neighboring circles are overlapping; the common areas with neighboring circles contain spindle-like colored pieces. By turns of the circles, the pieces can be moved around.

The puzzle is absolutely trivial, it can be seen as a mechanism for creating nice patterns.
