BookBook is a hand-distressed hardback leather case that disguises your MacBook, MacBook Pro or MacBook Air laptop as a vintage-looking leather-bound book. The case was created by Twelve South, a company that specializes in Apple (only) accessories. They have also made versions of BookBook to disguise iPads (link) and iPhones (link). In addition, designer Anna Sui will be making her version of BookBook available in the future.
