I feel a little like I'm encroaching on Jellio's territory by posting about furniture. But while I can't claim to be an erudite “man about town”, I fully acknowledge my geekier tendencies.

Which is why I put these Tetris Shelves into the “man, I wish I'd thought of that first” department. Not that much info on the web site, but I'm guessing they come in modular pieces and you can stack them just about any way you want. These would look great in a narrow wallspace. (I hear they are incredibly expensive though, so it may be quicker to make a quick visit to the Home Depot and build your own).
