This is really clever. I like the idea of using ball bearings to keep the gears turning smoothly. I've been trying to come up with a way to rig up a gear system for a few designs I've been working on, but I kept getting too much resistance in the gears no matter what I was trying. I never thought to try bearings though. Very nice all around, congrats on the win too.
