On random days this month, Tilda Swinton (actress, Bowie-enthusiast, badass) will be performing her 1995 piece "The Maybe," which consists of Swinton sleeping in a glass box. In fact, at this very moment, Tilda Swinton is sleeping in a glass box at MoMa for your viewing pleasure.

Gothamist spoke with a source at MoMA who told them that the "Museum staff doesn't know she's coming until the day of, but she's here today. She'll be there the whole day. All that's in the box is cushions and a water jug."

Swinton first performed "The Maybe" in London, followed by a repeat performance in Rome.

MoMA describes the piece's random schedule:

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.
