His skyspace in Tempe is a slight departure, in that Turrell relies both on the light of the sky and on man-made light and color reflected on the large-scale frame that's suspended by a metal structure surrounding the installation. The colors change periodically and the best time to sit and watch the show is half an hour before sunrise and/or sunset, when the color of the sky and the color of Turrell's frame change most dramatically.
Turrell's other big, current (and ongoing since the 70s) project is in the Roden Crater in Northern Arizona, where he has reshaped the a volcanic crater into what he calls a "celestial vaulting." The visual experience of the audience inside of the crater is a dome-like appearance of the sky rather than the flat horizon. The crater is not open to the public, though Turrell has taken a few small private parties into the space to see what he's been working on.
We'll post more information about Turrell's latest work as soon as it's released by ASU. In the meantime, take the trip and watch the show.
