The Compiz window manager is available on Fedora 10. Since Compiz uses 3D graphics acceleration via Fedora's OpenGL libraries, you will need a descent graphics card (and their drivers) installed on your Fedora system. For more information on Compiz see: http://www.freedesktop.org/wiki/Software/Compiz
