The Voronoi Bookshelf by Marc Newson is made from a single slab of white carrara marble. The organic shape gives the eye a welcome break from the monotony of rectangular shelving. Owning a unit like this would force you to look at your personal objects in a whole new way as you hunted for the right alcove in which to put them. This is a fantastic piece of design that will no doubt have lasting appeal. I have no idea how this would make it into the average home, but perhaps Newson liked the irony of using a totally impractical material for such a banal piece of household furniture. A shelving unit turned into glorious sculpture! I would not be surprised if it is reproduced in a more practical material in the future.
