An anonymous reader writes "Unlike most Bond villains, 70-year-old James Turrell has turned a 389,000-year-old extinct volcano into something other than a secret hideout; he's turned it into a naked-eye observatory. From the article: 'Inside, the crater's naturally lit viewing rooms are precision-engineered to observe specific celestial events. While outside, Turrell has reformed the rim of the crater to create a beautiful "vaulting effect" of the sky in a way that we almost never see it. "I'm very interested in how we perceive, because that's how we construct the reality in which we live," Turrell says, "and I like to tweak that a little bit. I make structures that arrest and apprehend light for our perception."'"
