Public art that turns cities into playgrounds of the imagination | Helen Marriage

Visual artist Helen Marriage stages astonishing, large-scale public art events that expand the boundaries of what's possible. In this visual tour of her work, she tells the story of three cities she transformed into playgrounds of the imagination -- picture London with a giant mechanical elephant marching through it -- and shows what happens when people stop to marvel and experience a moment together.
