Earlier I post a link to a way to add actual movement to a turning - that I accidently stumbled on. Thought it'd be interesting to incorporate a bearing I had that was part of a router set. The hope is that the bearing will let the "box" spin - by just blowing on it.
What I hope this gets acrossed is that working movement into pieces isn't hard to do - and is fun. Maybe YOU will do a piece that moves.
