So, does that mean you're a little twisted?

Of course you know that I'm just kidding. I would never say anything mean about people who are developmentally-challenged or about mechanical engineers. No, never!

Excellent work on the scene. You have been able to do something that I am still struggling with. I think my method is simply not doable, but I'm going to continue to work with it until I A: Get it to work, or B: Give up on it.

I am a little twisted, but it's a family secret and we don't talk about it much. Anyway, the puzzle didn't work so well until I redid it with slight clearance on the guide rails (0.005m on a 2.5m radius).

its hard to move the =P

If you could make some version incorporating hexagons, that would be amazing.
