"Tilda Swinton will be doing unannounced, random performance art pieces sleeping in a glass box in the museum," the source added. "Today is the first performance. Each performance lasts the whole day the museum is open." Swinton and her box are located near the ticket collectors today, but the box may be in different locations at other performances.
"The Maybe" was first performed in London in 1995 at the Serpentine Gallery; Swinton conceived the performance piece, and asked artist Cornelia Parker to collaborate on the installation.
