Ah, construction sites, the noisy and oft-rat-infested bane of an urbanite's existence. Over the past two years, several organizations, including ArtBridge, the Center for Architecture and NYC's Department of Buildings, have transformed scaffolding and other eyesores into public art installations. And tonight you can hear artist Maya Barkai, ArtBridge founder Rodney Durso and others talk about the trend. True, prettier construction sites won't muffle the relentless sound of a jackhammer at 8am on a Saturday. But at least the place will be more pleasing to your bleary, dark-ringed eyes.
