The Aakkoset bookshelf from Kayiwa might not be the most efficient way to store your things, but the alphabet shelf sure would get a typographer excited. Look at how useful a well constructed 'W' can be!
The Aakkoset bookshelf can double as a room divider and if you don't want to clutter the letters, you don't even have to add stuff to the shelf. I mean, It's a conversation starter on its own.
It's mildly funny that some letters, like S, are incredibly useful in real life but not at all useful as a shelf design. In fact, I think it's useless. The shelf comes in black, blue, green, orange, red, violet, white and yellow. [Kayiwa via Unplggd]
