Got very interested recently in a video I saw running thru my feed:
Well, I got very intrigued about the physics of it and wanted to know your opinion about my guesses and how to proceed regarding them. I think that basically this mad motion is due to the fact that there's some ratio between the length of these pendulums. I spent a little time thinking and before solving the movement equations thought that maybe I couldn't use the approximation for small angles for that and MAYBE the initial motion would be related to a trasient term (indicating time interval which the system is oscillating for angles greater then 5 degrees) and then go to these repetitive patterns, for smaller angles in which the system is pretty much conservative). I thought about solving this numerically in Mathematica, plotting multiple pendulums with different lengths.
