The Beauty of Chaos

It's something along the lines of what I think is called "dual periodicity pendulums."
.
And yes, I do believe there is mathematics that can describe and even predict this. The YouTube channel 60 Symbols touched on it in one of their videos a little while back.

the reason it's chaos is you can change the start position of either joint by a tiny fraction and it completely changes the pattern

A complete picture would be a completely filled blue circle with a red outline of a circle inside.

ahhh thank you that is very satisfying to know
