Ever get bored of looking at that same brown desktop background? Yep, so do we. There are literally thousands of themes out there for your Linux desktop to make it look different. Some people take it to the next step and even change their Window Manager or Desktop Environment, a choice that poor Mac and Windows users don't have. Still, if you're not quite sure you want to take the leap and change from GNOME to KDE or from XFCE to Fluxbox, there are certainly plenty of things you can change to make your favourite desktop look nice.
This link is aimed squarely at Ubuntu 9.04 users running the default desktop, Gnome. If you want themes for KDE, try looking at kde-look.org.
