Howtoforge posted a tutorial about enabling Compiz Fusion on an Ubuntu 10.10 Desktop with NVIDIA GeForce 8200 graphics card

This tutorial shows how you can enable Compiz Fusion on an Ubuntu 10.10 (Maverick Meerkat) desktop (the system must have a 3D-capable graphics card - I'm using an NVIDIA GeForce 8200 here). With Compiz Fusion you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop.
