Your local science museum might offer a “Night at the Museum,” where kids in sleeping bags cuddle up alongside the stuffed mammoth diorama. But at the Guggenheim in New York, an overnight at the museum becomes an act of performance art. A centerpiece of the show “theanyspacewhatever,” opening next week, is Carsten Höller‘s Revolving Hotel Room, a hotel suite on four rotating platforms, smack in the middle of the museum. Make a reservation, show up in your pajamas if you like, and become art while you sleep. The show run October 25, 2008-January 6, 2009. Reservations: 212-360-4373.
