Under suggests the feelings and sensations that relate to looking up at the surface of the water while submerged beneath it. One of the most prominent aspects of this is an image of the bubbles ascending from breathing out. The work consists of a round image projected on a screen suspended from the ceiling. As the viewer is detected moving under the screen, a torrent of bubbles rising to the surface of the water erupts. Pausing causes the imagery to settle down to be a soft rippling image of the sky seen from under the water.
The bubbles are louder and longer if the sensed activity is greater than past detected events. When the sensed activity is less than that of past events the bubbles played are quiet and softer.
