Thanks to the real estate bubble bursting and the ensuing recession, there are tons of vacant retail spaces all around Manhattan. What to do with all this prime space? One solution is to cover it with illegal advertising.

No Longer Empty has a much more elegant solution. The group is working with landlords to turn vacant storefronts into temporary art galleries that are free and open to the public. They currently have a gallery in the ground level of the new Caledonia luxury hotel on 16th Street and 10th Avenue by the High Line. I checked it out last week and it was awesome. What a novel idea! Using empty space for the public good!
