In the gallery there is an image projected down onto a bed of sand and an image on the wall. When there is movement in the gallery the imagery on the floor projection is of waves rolling to the shore, with accompanying sounds. When the system senses that the movement has ceased, an image of a wave breaking appears on a wall of the gallery and the sound of a wave envelops and fills the space. If there is a continual lack of movement, the image on the floor becomes a quiet, soft blue blurred image and the wall image disappears.
When the syste senses that recent activity in the gallery has been more than the historical average, the waves that appear on the wall are softer. In the opposite case, the waves that appear on the wall are harder. The less a viewer moves, the fiercer the wave; the more the viewer walks around the installation, the more softly the wave breaks.
