In this idealized environment the end result (no friction or air resistance) just looks sort of pretty but I guess still interesting when viewed from different angles. The period of oscillation is proportional to the square root of the pendulum length. The patterns depend on the lengths.

Deriving lateral patterns for a given string length sequence could drive the the nuts out of an undergrad physics or maths student in an exam. That would be cruel.

Yes MJF it is and I did as I said get carried away with working on the theory from an ideal scenario ie there is no friction either from a mechanical or air resistance angle or the absence of any gravitational or time / space influence.

I still think that Jed had a very original idea and I really admire the work that he put into the graphics.

I think the Italian scientist Galileo first noticed the regularity of a pendulum when observing a moving chandelier in Pisa cathedral circa 1600 and he later worked out the math. Story is he timed it with his pulse. Maybe it was a boring church service.

My C4D animation was a kind of thought experiment. All the laws of physics are obeyed. In reality it would be hard to make such a device because even with some clever engineering to lift the pendulum weights, the pendulums would probably collide. Would make a cool Newton's Cradle type executive toy.

I say respect to Maxon for including real world physics + dynamics in their modeling software.

edit - found a video of a real life version of my pendulum rig

I didn't realize it was your animation. VERY well done.
