All of the Lights: James Turrell at the Guggenheim
Talk about trippy. James Turrell's new museum-spanning retrospective at the Guggenheim features a massive installation, Aten Reign, that turns the entire Frank Lloyd Wright atrium into a colorful pulsing eye of light. Just chill out under that for a few hours.
Thru Sep 25. 1071 5th Ave. (E. 88th St.), Upper East Side (212-423-3500). $18 here.
