Do you have any plain interface CDs at home? I still remember i have plenty last time. Me and my friends use to draw something on it and stick it on the wall and door. Somoene came out with an idea of making your CD cover by using only a few tools, a walkman, a couple of water-based or permanent marking pens and a clip.

Take a look at the tutorial here and probably you could get to make one yourself in the future.
