Showing every CD cover for a shelve = A waste of space.
If you think about it...the primary reason shelves are made is so that it stores things in a minimum amount of space, not to spread it out. o_O'
Either use a regular CD Shelf and just have one CD on display for each block of the shelf and change it to your liking...err, like this?
Or buy those ones that goes across the edge of the wall like they use in some CD stores (haven't seen a Western CD store use it...so I'm not sure if you know what I'm talking about). But if you bang the wall hard it'll probably all collapse though...because there's only a little bit which holds the CD in place...
Umm, look around in IKEA, they have loads of CD storing devices. Good luck finding such a weird item. o_O'
