The installation spans three adjacent rooms. The first of these is a large gallery bathed in yellow monofrequency light, flooding in through the skylight, which reduces the spectral range of the viewers' vision to duotone. The second room is accessed via a passageway and lined with blue sheeting, the color of which is only apparent when viewed from the naturally lit second space. Passing around a blackthorn hedge, visitors reach the final gallery, where a boulder sits on the floor; above it is a fan which, suspended by its own power cord, propels itself around the space.
