Remix with your own background! The ball bounces off anything drawn in black. This is a far-from-perfect attempt at making a ball react to whatever background is displayed on the stage (or, more specifically, to the black parts of the stage). Unusual and unexpected things might happen from time to time and the ball never properly settles but, that apart, it's definitely a bouncy thing to watch! It was a quick test project so don't expect too much! Toggle debug details with space bar. As per @PutneyCat's request, you can now pick up and throw the ball.
