"The US Patent and Trademark Office today published a collection of Apple filings, including a 3D interface that may herald the most radical - or, dare we say, the most bizarre - usability development since Doug Englebart first demoed a window-based GUI 40 years ago yesterday. Described in excruciating detail by AppleInsider, the "Multi-Dimensional Desktop" application, filed on June 8 of last year, describes a 3D workspace - "desktop" being a wholly inadequate term - in which the familiar 2-dimensional GUI is joined by a floor, ceiling, and right and left walls, each capable of displaying interface items such as windows and icons."
