In order to make Ubuntu Linux look cool, you need to install the compiz fusion plugins.
Open a new terminal window and type:
sudo apt-get install compiz compiz-plugins compiz-gnome compiz-core emerald compiz-fusion-plugins-main compiz-fusion-plugins-extra fusion-icon compizconfig-settings-manager
When the installation is complete all the effects are available under the System->Preferences->CompizConf Settings Manager.
