While in Phoenix we visited two art installations by James Turrell, an artist whose medium is light and space. His structures are called skyspaces.
The first exhibit was at the Scottsdale Museum of Contempary Art , called "Knight Rises." You view this before , during and after sunset. You sit in an oculus and stare up at an opening in the ceiling. The focus is on the changing sky as night " rises" - actually rather cool.
The second one was at Arizona State U, near the Interdisciplinary Sci and Tech bldg, and it's called "Air Apparent." Love the play on words. Again, it's best viewed during sunset (or sunrise.)
Tomorrow, the Tribe and spring training.
