"The Real World" meets No Exit: audiences circulate around the exterior of a fully functional house, watching the ever-changing action through the windows, and coming and going as they please. Habit is a durational installation created by provocateur David Levine (previously at PS122: Anger at the Movies, Venice Saved), with a commissioned text by playwright Jason Grote (NBC's "Smash") and environment by Marsha Ginsberg. All day long, within the four walls, actors re-complete the drama, on an endless loop, making up staging to suit their needs. When they're hungry, they eat; when they're dirty, they wash. Habit is a free event, available from 1:00pm-9:00pm on participating days; reservations are not required.
