I wonder if this is what happens when a number of persons jump on a trampoline in and out of synch with each other. It can get rather chaotic at times.

“Imitation is the sincerest form of flattery.”
I wholeheartedly agree. And since your execution is much cleaner (as always) than the polygonal salad I usually slap together, I really have no reason to complain. On the contrary, I have to thank you once again for improving one of my concepts. Please feel free to keep doing so with any scene that inspires you.

Xray,

Sort of. Each person on the trampoline is like one of these masses with its own “natural” bounce frequency, and the trampoline surface is like the driving bar. When people jump in sync with the trampoline’s motion (or with each other), you get large, regular oscillations—like resonance in one of the springs. When they’re out of sync, their forces add and cancel in complicated ways, so the motion looks irregular and “chaotic,” even though it’s all just the superposition of many simple oscillations. This scene is basically a clean, 1D version of that messy trampoline behavior.

T_Reißig,

Thanks for the understanding, kind words, and encouragement.
