LEGO GBC Module : Heptagram

A combination of 40 gears and 140 internal gears rotates 3.5 times during the revolution.
After making exactly two revolutions, the orbit forms a {7/2} heptagram.

Amazing work as usual. I love the smoothness of the motions on this one and the fact that it take 2 full rotations before the ball is released.
