Running linux? Want a nice desktop customization?

Hey so I did this video a while back. I see alot of people talking about linux and saying they wish there was more customizations they could do to the desktop. Well here is cairo dock. Its like a dockbar that you see in mac os. Except there are plenty of different themes you can choose from. http://www.youtube.com/watch?v=1ZggMRCPwaw
