Yesterday I received the latest issue of Smithsonian magazine, which has a fascinating article about an artist named James Turrell who has been constructing a sort of light-sculpture (for lack of a better word) inside the rim of an old volcanic crater in Arizona. If you've ever been intrigued by ancient architectural structures like Stonehenge or the Pyramids, especially their relationships to the skies, you'll no doubt find it an interesting read. The only disappointment is that the structure is not yet completed and is not open to the public (yet).
