It's nap time for Tilda Swinton.
The Academy Award-winning actress and recent Davide Bowie music video star is performing art on an unexpected display at New York's Museum of Modern Art. The display is called "The Maybe" and involves Swinton sleeping in a glass box in front of museum attendees.
MoMA said in a statement, "An integral part of The Maybe's incarnation at MoMA in 2013 is that there is no published schedule for its appearance, no artist's statement released, no museum statement beyond this brief context, no public profile or image issued. Those who find it chance upon it for themselves, live and in real-shared-time: now we see it, now we don't."
The display includes cushions and a water jug for Swinton and if you don't happen to catch her asleep, you can see the live art here.
