How do I write and plot Chaotic Scattering

Hello! I was trying to write a code of Chaotic Scattering and plot it, but could not find any sources or examples. Maybe someone could assist with it? I have the idea which is line being scattered off of multiple surfaces and bouncing arround. Something, which is implemented in a pinball machine perhaps. Any help would be much appreciated! I imagine the main principle is something like this: https://www.youtube.com/watch?v=tqpXGlEEn8s
