Secret Elevator Bookshelf by Machine Project
This is by far the coolest bookshelf that I’ve ever seen. Machine Project has found a way to solve the problem of having furniture invade too much space by making it retract in to the ground. Aside from the cool aesthetics and fun factor of being able to pull your bookshelves up and down at will, this thought process can be reapplied to many items that take up too much unnecessary space. Foldable dishwashers, anyone?
