In 1968, Ivan Sutherland of Harvard University created the first stereoscopic computer display (nicknamed the "Sword of Damocles" for the unwieldy size of the apparatus that hung over the user's head). Sutherland's experiments with virtual worlds began in 1966 at MIT's Lincoln Laboratory, and they culminated in the invention of the first 3D head-mounted display and the first virtual computer environment, a wire-frame simulation of a room (shown here).
