Google Maps Street View now lets you review old Street View photos and compare them to recent photos. This is a feature our former Director of Production Derek Lloyd would have loved. He was a big fan of Street View and even created a 3D mockup of the PS122 building in Google Sketch Up. Looking back at 150 first avenue in 2007 (just click the clock icon below the address in the upper left hand corner) you can see the old scaffolding that defined the building for a decade. And now you can see the nice new facade and signs of the interior renovation- very cool.
