This program shows some bouncing balls while the camera floats around the platform. There is a skybox background, but you can't see it too well. Strangely, the balls tend to gain energy as time goes on. I think it is a side effect of using discrete time intervals to simulate the physics (Its really not a pretty system). This runs quite fast on my computer, but runs somewhat slow on some others, partly due to the fact that the spheres are very high resolution (and are being regenerated each time).
