James Turrell

Turrell is an artist who uses light to form optical illusions and challenge people's perceptions. For the past 30 years he has been working at Roden crater, a dormant volcano in Arizona. Turrell alters pieces of wall or ceiling to make the light filter in a space at a certain angle, a technique he calls skyspace. This project wont be completed until 2012. Turrell has balls, to take a volcano, dormant or not, and sculpt it into your own artwork is about as badass as you can get.
