Great fun if you're not too busy. http://www.thecleverest.com/content/attractors.html You can move and tilt the plates and achieve almost perpetual motion.
No "almost" about it.The system doesn't conserve energy. The collisions with the plates are obviously inelastic but the balls don't stop if they're in the presence of the "attractors"; they're apparently getting a "kick" from something in the course of orbiting.
See attached; it's still going on my desktop, and the balls never escape to get dropped again. But they also don't slow down or stop, despite bouncing on the bottom plate from time to time.
