Skins
Empathy Jukebox (was) is skinnable.
The example skins are available in the downloads section. The .SKN skin files need to be extracted into the program folder. You should be able to create your own by extracting and replacing the bitmaps in a skin file with your own. The .SKN files are merely .DLL files with the extension changed. You could use a tool such as resource hacker to manipulate the skins. I'd love to see what people with some artistic talent come up with.
