A Sun "virtual prototype" of a futuristic computer. It took the form of a desk whose horizontal surface curved up vertically at the rear, and the entire surface was a combination display/touchscreen/scanner. This prototype was not physically built, but created using special effects for a Sun propaganda video. The demonstration involved some rather advanced software, much of which has also yet to be really built. More info at Bruce Tognazzini's site: http://www.asktog.com/starfire/starfireHome.html
