The author, going on his seventh hour of observing.
Art changes the world.
It changes the way we see and understand even the simplest things. It alters your perception of the sky, and not subtly, but drastically. Around the edge of the room is a bench to sit on, lean back and watch the sky through the hole. It sounds simple, but Turrell has stacked the deck, forcing you to see things you normally would not. By focusing your attention through the frame of the hole, you can see things that pass unnoticed in ordinary life.
