Ball Bounce Physics with spin

Bouncing superball simulation with spin on arbitrary 2D surfaces. Simulates frictional collisions of a spinning ball against arbitrary surfaces. New surfaces can be added by the user to set up any scenario with multiple surfaces while the simulation is running and the ball can be throw by the user from a given position and with a given velocity. The coefficients of restitution can also be changed while the simulation is running. The trajectory of the ball can be traced.
