"This tutorial shows how you can enable Compiz on a Xubuntu
11.10 (Oneiric Ocelot) desktop (the system must have a 3D-capable
graphics card - I'm using an NVIDIA GeForce 8200 here). Xubuntu
uses the Xfce desktop environment which is a fast and stable
alternative for those that are not happy with Unity or Gnome 3.
With Compiz you can use beautiful 3D effects like wobbly windows or
a desktop cube on your desktop."
