I did a very similar thing to what dragoon did...my friend and I were playing in the student union of our wonderful university and saw a whole box of AOL CD's lying on the floor. My friend is a klepto, so we ran out of the union with them. We had about 400 discs (we counted). Then we took them all out of their plastic, threw all the packaging away (finding out in the meantime that they all have the exact same password/access number codes on them), and tiled the ceiling of my dorm room with them. My roommates, though not all cool at the time, were cool with mirrored ceilings. This worked for a while but the masking tape didn't hold. :(
