The following bookshelf, created by Portuguese designer Arco da Velha is certainly one of the most interesting book organizers I’ve seen lately. We’re not looking at a regular bookshelf design as the Waves features uneven shelves made with bended wood. The Waves will let you store various books and objects of different sizes considering the uniqueness of its shelves. The bookshelf comes with its own set of wheels, a pair of them placed on each side, with a proper braking system in place. In other words the Wave can be immediately moved around the house in case you absolutely require having it parked in a different position on a whim.
