Aqua and XFree86

A free version of XFree86 running side by side with Mac OS X's Aqua GUI is now here! Thanks should go to all the members of the XonX team for making this possible and continuing to improve things. At any given time, a current snapshot of the code can be found in the XFree86 CVS repository.

The Aqua implementation, using CoreGraphics, shares as much code as possible with the pure Darwin implementation, using the IOKit. You can download the precompiled binary version or you can build it for yourself.
