This is a simple bouncing ball screensaver. I was surprised to discover that there weren't many of these
around. So I thought I'd write one only to discover that the collision detection and response was more
complicated that it looked. What sets this screensaver apart is that it has some interesting scenarios.
Special thanks go to Lucian Wischik for his original threaded timer, and to Dave Eberly for his explanation of collision detection.
