Simple Sinai Billiard

The program has two different modes:

two adjacent Sinai Billiards with the possibility to choose freely the initial conditions and the speed of the animation

seeing a histogram evolve which shows how often each pixel of the billiard is visited by the particle (i.e., you see the convergence to the ergodic measure)

The program is licensed under the GPL. At the moment only a source version is available: sinai.tgz.
