In this clever simulation, bouncing balls obeying the laws of physics somehow arrange themselves, mid-chaos, into neat patterns. This is immensely satisfying.
Spoiler: the trick here is a pair of simulations stitched together, like a physics Texas Switch: “Each sequence is obtained by joining two simulations, both starting from the time in which the balls are arranged regularly. One simulates forward in time, one backwards.”
