series of images plastered or painted on a concrete wall that is designed to look like a rocky cave. First, there is a drawing on a piece of paper of a bald man with a long white beard, sitting in a tub of water. The man is holding a saw above his head. Next, the camera pans to the right to show a series of indistinct black patterns on the wall. Finally, the camera shows a drawing of a woman in a leotard, jumping with a ribbon. All of these images are partially obscured by the artificial rock wall.
