A little Christmas Day diversion for those who never stop thinking about cities.
Via Twitter, Chris Wong announces the launch of Urban Scratchoff—a website that provides a new way to reveal the changes in New York City over its history.
Urban Scratchoff is a simple, interactive map: two layers are provided and you simply click and swipe over the map to "scratch off" the top layer. Swap the order of the layers to go from 1924 to present day, or vide versa.
