Swinton sleeps in glass box in New York art exhibit

Tilda Swinton is sleeping in a glass box in the Museum of Modern Art (MoMA) in New York City.

The 'Moonrise Kingdom' actress is the star of a new performance art installation called 'The Maybe', that involves her spending her days snoozing in the transparent box, simply equipped with a mattress, bed sheets and a jug of water, in front of visitors.
