Visitors to the Museum of Modern Art in New York are getting the chance to see an unusual performance: Oscar-winning actress Tilda Swinton sleeping in a glass box.
For a performance piece call "The Maybe," Swinton wore a light blue shirt, dark blue trousers and shoes while lying on white bedding with eyeglasses beside her.
"Living artist, glass, steel, mattress, pillow, linen, water, and spectacles," a description card said.
First performed in London in 1995, the performance piece will be repeated periodically throughout this year, museum spokeswoman Margaret Doyle said.
"The nature of the concept is that it not be announced in advance, nor publicized by the museum," Doyle said.
Swinton, 52, won an Oscar for best supporting actress in the 2007 film "Michael Clayton." Other credits include the title role in "Julia," "Burn After Reading" and "The Curious Case of Benjamin Button."
