If you happened to be visiting New York City's Museum of Modern Art (MoMA) on March 22, you likely stumbled upon a most interesting scene of Oscar-winner Tilda Swinton resting inside a glass box. 

The exhibit, titled "The Maybe," is an eight-hour still life piece conceived by Swinton back in 1995 and since performed in museums in London and Rome. According to officials at MoMA, Swinton is expected to appear within the glass box, which features nothing more than a bed and a jug of water, an additional six times until the end of the year. 

"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," officials said in a statement. "Those who find it chance upon it for themselves, live and in real — shared — time: now we see it, now we don't."

A description for the exhibit states Swinton's name and reads: "Living artists, glass, steel, mattress, pillow, linen, water, and spectacles."
