Attack Of The Clones is yet another theme created by JurialMunkey (who is also behind Divergence IV: A New Hope) that features a unique Metacity theme and a very interesting combination of light and dark colors.
Attack Of The Clones requires Murrine Engine 0.98 (which is available in Ubuntu 10.10) - if you're using Ubuntu 10.04, install it using the following commands:
sudo add-apt-repository ppa:elementaryart/elementarydesktop sudo apt-get update sudo apt-get install gtk2-engines-murrine
To install the theme, download the .zip, extract it, then open the "Appearance Preferences", switch to the "Themes" tab and drag and drop the extracted .tar.gz file onto it.
