A mystery billiard

This simulation implements a game idea due to several viewers: it shows the evolution of 20,000 particles in a billiard that is not visible. The aim of the game is to guess the shape of the billiard, which becomes easier as the simulation goes on. The shape of the billiard is revealed at the end of the simulation. Have fun! Edit: the answer is given at the end of the description.

All arcs have the same radius, but they alternate between curving inward and outward. This creates both dispersing and focusing effects.
