I did one ages ago, not all that complicated, but does exactly what you're
after.

It renders quite fast, fast enough for me to make a fifteen second 
animation of the ball soing a twirl in various directions and coming back
to it's original state, it looks great when you loop the animation and 
play music and turn the lights off in the room, my own private disco.
