This geodesic dome sits on the floor of the Exploratorium, a science museum in San Francisco. It was created in 1971 by August Coppola (brother of director Francis Ford Coppola and father of actor Nicolas Cage) and Carl Day, who wanted to create an environment in which only haptic perception could be used. The inside of the dome is pitch black; visitors must crawl, wiggle, slide, and otherwise navigate the unfamiliar terrain using only their sense of touch. How would you feel being in that environment for an hour or so?
