ball hits a pointy bit, what happens?

Miscellaneous Forums/General Discussion/ball hits a pointy bit, what happens?

It bursts!

Seriously, i would try adding a kind of chaos system that mabe sticks in some kind of randomness to the deflection.
You could add a bias to the randomness by using the center of the ball in relation to the vertex on the corner.

Other than that, no idea :/
