James Turrell's Perceptual Cell or to be specific Light Reignfall is now booked into August. I've written about what the experience entails here, but it's quite amazing as the main exhibit hasn't even opened yet at LACMA. The exhibit begins May 26th, but this part is now booked for two solid months before it even opens.
Light Reignfall is hard to describe, but from the picture on the right it looks like something out of science fiction. The women in white lab coats are just such lie in being needed. Live the lie and try and get reservations for August, but it's expensive.
LACMA Members $15
General Public $45
