Well, it happened. Somebody did it. That somebody is Belgian designer Filip Janssens and "it" is a bookshelf that stores a single book. In this carefully arranged photograph, the book is splayed open, which is a bad way to store a book. There is also a pair of glasses (smart) and a glass of water (why). We're not going to say that this is the worst bookshelf ever, but we will say that we are unreasonably upset about it.
There are also alternate versions of the shelf, one of which can store up to six books if you're a really heavy reader.
