When I was in college a million years ago, I had a class in Chaos Theory.

The professor knew I worked on sets for the theater group, and he wanted me to build a full-size double pendulum that someone could ride on. I pointed out that it would likely kill the rider, tear itself apart, or both.

Instead I wrote a double pendulum simulator. You could adjust the weights and lengths for each pendulum and the starting position. Run it with the exact same setup and see the exact same result, or make a tiny, tiny change and see the motion was completely different.

I think I still have it somewhere. On a 3.5" floppy disk. Borland TurboPascal.

Why would you film this in front of two device plates that are not level?

Because I was really excited and my apartment sucks, it is what it is

Fair enough, the device is neat!

But did you notice the gorilla?

Hell yeah. A back burner dream of mine has been to create an analogue double pendulum input for modular synth

was working with led & photosensitive ideas lately. Used as a manual “one shot” for whatever…more of a novelty piece more than anything

Kept waiting for it to balance vertically upwards based on trama from control systems labs.
