I've used pool as a vehicle for illustrating motion blur myself -- this is a very good example. Because you have such good "tracks" of the "particles" I'd have been tempted to title it something like "Large Hadron Collider: Home Model" ... ;-)
Fabulous idea and good execution. I think you will be unhappy with the processing. The black velvet cloth needs to be so much darker to make the balls stand out accentuating their geometric movement and trail. As difficult as this was to shoot, I'd be giving it +1 if a ball sunk on the break :)
