Clark's mask holds small movable mirrors in front of the eyes, juxtaposing and fracturing reflections of the self and the surrounding world. Sutherland's pioneering work with virtual reality, developed around the same time, was based on the introduction of stereoscopic head-mounted displays. The visual and cultural parallels between these and other investigations in art and science are as significant as they are unexplored.
