Run in Flash turbo. Enter a number- the number of balls on screen. For non-turbo use, I would recommend 3 or 4, but downloaded in turbo mode, 10 will work pretty well. This uses the equations for elastic collision to calculate the balls' velocities, and lists to store the different variables. Try running 20 in Flash player on turbo speed (shift+click green flag). This project works pretty well in the experimental viewer.
