There's never a bad reason to pedestrianize a full city block for a month, so why not shut down Broadway between 37th and 38th Streets for a fun, interactive art installation? Now through January 31st, the Garment District Alliance has done exactly that, with the placement of a dozen giant, illuminated seesaws right in the middle the road.

The installation is called "Impulse," and arrives via a touring public arts organization called Creos, based in Montreal. Each of their 12 over-sized seesaws measure between 16 and 24 feet, and the LED lights and electronic tones are activated when the apparatus is set into motion.

It's all part of the Department of Transportation's Seasonal Street Closure Program, which seeks to "expand and enhance the pedestrian experience" in some of the busiest parts of Manhattan. "There's been a learning curve for drivers with the new bike lanes, the pedestrian plazas, and the street closures," said the Garment District Alliance president Barbara Blair, "and the more of this sort of thing you do, the more you maybe dissuade people from using a car."
