Actress Tilda Swinton stunned onlookers at New York's Museum of Modern Art (MoMa) on Saturday (23Mar13) by spending the whole day sleeping inside a glass box.
The Michael Clayton star entered the venue when it opened and took up residence in the art installation, named The Maybe, until it closed.
A statement from the museum reads, "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."
Swinton first performed the piece in 1995 at London's Serpentine Gallery, collaborating with artist Cornelia Parker on the project.
