Okay, so it's a radial piston dancer!

I preprogrammed a dance routine in order to show off some of its moves. You can delete my program commands and configure your own dance routine.

Instructions are in the scene.

(Yes, this scene is rather strange, but it may give some of you guys, who use a lot of Thyme script in your scenes, some ideas on how to make a simple programmable object scene. Instead of a stupid piston dancer, you might want to make a programmable robot arm (for example) using this technique.

UPDATE: Deleted unused code.
