this page showing a keyboard that gives whole new meaning to "flexible". No, it's not one of those rubber sheet thingies -- it's a keyboard where every key is an LCD screen, so the function (and language) of each key can change on the fly. Examples shown are between English and Russian, then Photoshop and Quake, with a revival of the left-side F-keys of the old AT keyboard to call up applications iconically.
At this point, the images are of a Photoshopped mock-up... But the FAQ column on the right side say they're after a 2006 release of a real object.
