A hut, too small to go into but large enough for some living thing to inhabit, was placed in one corner of a small room. The floor was covered with black painted paper, and the windows with tracing paper to give a diffused natural light. One of the walls was painted grey. In front of the hut an area about its’ size was marked out on the ground, and a grey piece of wood about a yard long linked the inside with the outside. A number of pieces of white painted wood formed a curved dotted line which went round the outside of the room, was obscured behind a mound of red earth, re-emerged, and then disappeared under a door. In the doorway there was a lens mounted on a stand through which the spectator could see the whole journey spread out and distorted.
