I don't know why, but I made a version of it using my Fast graphics scenario, and I think the circles look nicer. Wanna give it a try?

Isn't this just what you covered in the "Shooting Rocks" post? Nevertheless, I'll be looking forward to learning how circles bounce off each other.

Shooting Rocks was about the intersection of a line and a circle, whereas this is about the intersection of two circles (which is actually easier).
