A runner will sprint through a London gallery every 30 seconds for the next four months in the latest art installation by British artist Martin Creed.
The installation, called "Work No. 850", is sponsored by Sotheby's and goes on display today in the neoclassical sculpture galleries of Tate Britain.
Creed, who won the coveted Turner Prize in 2001 with an installation that was a light bulb going on and off in an empty room, explained in a statement: "I like running. . . . It's an example of aliveness."
Tate Britain director Stephen Deuchar called the work "compelling, simple and lyrical. It upsets any preconceived ideas of how to move appropriately through an art space," he added.
