Gassenhauer is an interactive room installed in @KCUA Gallery, Kyoto, that is operated by closing your eyes. It uses Kyle MacDonald's FaceOSC to recognise basic facial gestures, which are recorded by a webcam above a mirror. This data stream is sent to MaxMSP where the blink is isolated and calibrated to the eye size of each participant so that when they close their eyes it triggers events: light, heat, and sound. Two 500W floodlights are positioned above the viewer and these will burst on when the viewer closes their eyes creating a warm glow. At the same time Carl Orff's Gassenhauer will fade in, leaving the viewer to appreciate a pleasant moment of introspection. On opening their eyes the lights and music abruptly shut off and they find they are staring back at themselves in a dark corner.
