Description

This demo shows how to use Quartz Extreme to provide borderless OpenGL content on the desktop. The code is fairly straightforward, and uses the NSOpenGLCPSurfaceOpacity parameter to mark the view as being transparent. Pressing 't' will fade the background and allow the ball to bounce freely at the bottom of the desktop.
