ANN Nine ball pool

[Thomas McGrath III]

You know if the collision detection that happens on the sides of the 
pool game could also work on, oh, let's say a round/square object then 
you could have Bumper Pool and then you could also make a Miniature 
Golf game.

I changed your code and made eight holes instead of six and that was 
real easy just to see if I could do it. I would love to have the balls 
hit an object and bounce off of them. Love Miniature Golf............

P.S. cool attempt....
