New York, New York

Hola - another new episode of Imagine, edited and presented by Alan Yentob, coming next Tuesday. British artist Cornelia Parker has been creating big installations from found objects since the 1990s, but this year she got a commission from the Metropolitan Museum of Art in New York. Her installation, on the museum roof, is called Transitional Object: PsychoBarn, made from bits of an old red barn, made to resemble the Bates Mansion in Hitchcock's Psycho.

So, obvs, "Alan Yentob follows the artist through the creative process: from the early planning to the opening night."
