Mystery billiard 3

This is episode 3 of our mystery billiard game. The simulation shows the evolution of 25,000 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.

(in French, some with a Spanish translation) Answer: the billiard is constructed by deforming the sides of an equilateral triangle to circular arcs. The radius of the arcs is chosen in such a way that they meet at right angles at the corners, so that fronts of nearby particles hitting a corner are not cut into pieces. This is similar to a Reuleaux triangle, but the centers of the arcs are not located on vertices of the triangle.
