If you are not familiar with James Turrell, I highly recommend that you look him up. As a lighting designer I find his work mesmerizing. This man has taken lighting, nature, and architecture and created some of the most interesting optical illusions around the world. The real experience is NOT in any photo, but in a realtime viewing of his work. The changing daylight (and/or electric light) creates a kinetic experience that can play tricks on your eye. Below are some static photos from his installation at a Friends Meeting House here in Philadelphia.
