I want my theme to look like this. How would I go about changing the colors to look like this or is there a theme that already looks like this that you? I am using Unity and Gnome Shell. Is there a theme for both those desktop environments? Is there an application for changing the colors? I'm using *Ubuntu 12.04 beta 1*.
