Lasers concealed in the walls of a darkened room project slices of coloured light onto fog released periodically into the air. Miniature vortices, currents, and curlicues of fog swirl around above the heads of the visitors, reacting to the body heat and motion of the visitors standing beneath the fog to involve them directly in the production of their surroundings. Audible within the room is a composition, written especially for the artwork by Hildur Gudnadottir, being performed live on a cello by a robotic arm.
