If you're going to make music on your desktop, you can't make it look much better than this. Flickr user Caroline di Paola combined blacks, whites, and lots of lights and knobs to create a stylish and futuristic audio-mixing workspace.
Audio equipment has a habit of looking pretty ugly, but quite a few devices can fix that problem. Caroline found quite a few exceptions in the Numark Mixtrack, Lexicon IONIX, and some simple black and white studio monitors. Not that you should pick your equipment based on aesthetics, but it certainly doesn't hurt your workspace if the equipment works great and looks nice.
