Cool 3D Desktop Effects on Ubuntu 10.04 (LTS) using Compiz and Compiz-fusion:

By default ubuntu uses metacity as its default windowing manager that provides us with some lighter and smoother Desktop effects, but  when it comes to real 3D support for the Desktop Environment compiz has much more support as compared to the metacity .

Ubuntu comes with the compiz installed by default on it all we need is to turn it on .
