The Artwork Team aims to enrich Ubuntu by designing high quality, original and beautiful themes to be available in the repo as an *alternative* to the default look.
To install these themes open a Terminal window (Applications -> Accessories -> Terminal) and copy+paste the following line:
sudo apt-get install community-themes
And thats all!! To change the way Ubuntu looks goto System -> Preferences -> Appearance and select the Theme tab. Now select the theme you want to use and click on the Close button.
