Howtoforge shows you how to install Compiz on Ubuntu 12.04

This tutorial shows how you can configure Compiz on an Ubuntu Linux 12.04 (Precise Pangolin) Unity desktop (the system must have a 3D-capable graphics card - I'm using an NVIDIA GeForce 8200 here). With Compiz you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop. Ubuntu (Unity 3D) must be selected as your desktop environment.
