NEW YORK - JANUARY 16: An image is projected on a wall during a public art project by artist Doug Aitken January 16, 2007 in New York City. The project, which opened today, will be projected on the facades of The Museum of Modern Art (MoMA) daily from January 16 through February 12, 2007, from dusk until 10:00 p.m. The work, called Sleepwalkers, explores how people experience memory and narrative in an urban environment.
