Show me someone who owns enough book storage, and I will show you a liar (or a philistine). Unfortunately, traditional bookcases are heavy, permanent and expensive. You cannot easily get more of them to accomodate your latest literary shopping spree. Designer Dany Gilles came up with an unusual solution to this problem. He created DIY modular cardboard bookcases that are cheap and easily movable. The product arrives to you as a kit of parts, from which you assemble sturdy display boxes. The elements interlock to create a bookcase unit or stand alone as structurally independent pieces. Made entirely from recycled scraps of cardboard, the storage system is also eco friendly. It is not water friendly, however, but that is its only flaw.
