BouncingBalls

Keep comments captured since I had to re-upload to share source code - jafish mik writes (6 hours ago): It's great to have this demo - it's a classic! Bouncing balls seems to be the first thing people write for any new graphics system, so it's surprising that it took this long for someone to do a Greenfoot version. Do you want to publish the source, so that others can play with it?
