Balls elastically bouncing in a two dimensional eggshaped mathematical billiard are shown. The egg contour is defined by x2 + 1. 6y)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.
