Really cool movement. I've also looked at your other mechanical sculptures, good stuff.

Tried to make an engine with this kind of mechanism but it had too much play, would be cool if Lego had a ring gear that could be used in a Cycloidal mechanism but alas the only way  found was with tank track wrapped around a tire; which was again was not stiff enough to make an engine out of.
