Air XY is an interactive multimedia installation commissioned by the 11th Annual Architecture Exhibition of the Venice Biennale in 2008. The installation combines real-time animation, sensors, fog, light and sound to explore the way hidden systems in the contemporary city increasingly shape our perception and bodily experience.

A large-scale interactive wall projection confronts and engages visitors passing by the installation. The projection acts as a clock, charting the passage of time. The animation consists of four different, entangled layers: (1) a base layer of changing interface views that pan from left to right over the surface and increasingly become blurred, (2) the clock, which runs over the XY axis on a grid of 24 hours (horizontal) and 60 minutes (vertical) and features a moving vertical second line, (3) a series of 12 signs/markers which randomly float across the screen and react to the passing of seconds and the presence of visitors and (4) partial images of the visitors, who are tracked by overhead cameras and projected onto to the surface of the screen.

When the visitors walk behind the physical screen they find themselves in a darkened space filled with fog and subtle noise. A series of images are projected onto the floor using the same graphic markers that inhabit the surface of the screen on the other side. A strobe is pulsed at intervals of 100 milliseconds such that the visitors at first only see the after image of the projected marker on the floor. As the room fills with more fog, the size of the projected markers grows larger and becomes more apparent in the air. Thus the combined media reveal another space, not one of a flat 2d screen, but a fleeting immaterial architecture of air.
