This is just a simple little demo that shows off using Quartz Extreme to provide borderless OpenGL content on the desktop. It was inspired by the Boing demo for the Amiga personal computer. While the original demo used color cycling and the Amiga's dual playfield hardware for moving the ball around, this demo uses an actual 3D object with real lighting. Unlike the original, this one doesn't include sound.


This sample requires OS X 10.6 or higher.
