All you have to do is upgrade from cinderblocks to glass blocks, and suddenly your constructions are pretty! Clear silicone sealer along the top and bottom sides of the blocks will help keep the shelves from slipping.
If you're really lucky and find some blocks made with an opening on one side, you can even run cord in from behind and light them from within -- the new LED Christmas lights are perfect, because they generate so little heat.
