The 3D world just got a lot brighter with the birth of Compiz Fusion, a powerful compositing window manager for GNU/Linux operating systems. Originally there was one project, Compiz, but the project forked into Compiz, and the unstable and unofficial fork of Compiz known as Beryl. Now, the two projects have been reunited for one amazing compositing window manager. In a nutshell, it adds effects to your desktop like wobbly windows (the windows actually wobble when you move them), a cool virtual desktops manager via a cube, and much more. For proof of how cool it is, just do a Google Video/YouTube search for “compiz fusion”.
Some would say 3D desktops are useless fluff; some swear by them. This article gives you an overview of today’s 3D desktop options, and how they can help you be more productive.
Barring that, you can still brag about your top-notch computer in front of those poor Aero Glass-limited friends of yours.
