Egg billiard

Balls elastically bouncing in a two dimensional egg-shaped mathematical billiard are shown. The egg contour is defined by x^2 (1.4^x * )^2 = 1 (equation discovered by Don M. Jacobs). 1. One ball bouncing inside the egg contour. 2. 10 000 normally distributed balls moving in the same. 3. Same as 2, but larger spread (standard deviation) in initial position and velocity. Music by @gpcbass . Song called BAYA_street and made today specifically for this visuals. Visuals in Python & FFmpeg.
