Many music lovers, such as myself, have an over-abundance of CD cases and cover art hanging around. The solution I can up with was to find some white boards that were being thrown away, remove the pen tray from the bottom, drill some holes, and screw the pen trays to the wall - thus creating a shelf that holds CDs perfectly.
I know I have always had the issue that my art seemed very small on my wall, but large art was very expensive. But everyone has CDs floating around - at least the people who would be reading this would. If you can scavenge the pen trays, as I was able, then the project becomes nearly free.
A couple more pics might put it in better perspective. I have had this up in my last three houses.
Sorry about the quality of this one. It is very old.
I didn't do a very good job in my current installation. I plan on redoing it in the next week.
A couple more pictures surfaced in my iPhoto:
These are from my college dorm room.
With my lame IKEA couch + grandma quilt.
Better view of the trays.
