You can move and tilt the plates and achieve almost perpetual motion.
Any idea what it's modeling? I.e., what's the attraction go as?
Doesn't look like 1/r^2, the orbits look too goofy for that. Looks like
it falls off locally a lot slower than 1/r^2.
And the collisions seem to be anything but elastic.
I guess I could dig around on the website and see -- prob'ly documented
somewhere...
