this is pretty cool!

Interesting.. Is this chaotic in the sense that a small difference in the initial position leads to a very different movement pattern?

Very cool !! Absolutely loved the hypnotic movement.

Yes, it's chaotic. See https://en.wikipedia.org/wiki/Double_pendulum (Though this one has multiple nested pendulums rather than just double.)

Thanks for the link, it has nice illustrations.

Simply beautiful, thank you for sharing. I'm sure Ed Lorentz and Francis Moon would appreciate. I'm thinking that, if the CG's of the individual frames cold be brought closer to the rotation axes, maybe the time it takes to settle down would increase substantially. But again perfect contraption as it is, just me thinking how it can be modified.
