Ron Arad's 'Bookworm' liberated the shelf from compulsory linearity. His "Fly on the Wall" freed it from a single fixed position, while "Moral Coil" allowed shelves to sway and bounce. The wheels easily transverse the room, touching the floor at a tangent while the shelves maintain their horizontal position. Loaded shelves can be turned easily or moved effortlessly between rooms. Wheel diameters, vertical and horizontal shelf divisions, and anodized alminium interior colors vary. Some wheels are open and see-through, or have radially sliding door punctured to give access to the shelves. In addition to the series of wheels there is a single "one off" stainless steel wheel bigger than the rest(220 cm diameter) that can slice, isolate, and shift a section of a room, along with its storage, shelves, and pigeon holes.

"The idea came from this little toy for kids that had the world floating inside a sphere the size of a Ping-Pong ball," says Arad, who developed the piece as an experiment at his North London studio, Ron Arad Associates.
