Are the stripes spinning . . . or are you? Exploratorium exhibit "Silage Beach," by Artist-in-Residence Mowry Baden. When a moving scene dominates your field of view, you almost always perceive yourself as moving and the scene as stationary. You assume that you must be moving because in normal, everyday life, you move through the landscape–it doesn't move past you. Come play at the Exploratorium! Now open at Pier 15 in San Francisco.
