It's often said that the only constant in New York is constant change, and glancing through historic photos of the city—even photos from just 20 years ago—it's evident how true this really is. New Yorkers love waxing poetic about the good ol' days and lamenting the loss of history, and a new app wants to tap into that nostalgia and let users time travel. Called Deja Vu, the app holds a collection of hundreds of vintage photographs that have been geolocated, so you can stand on a street corner and pull up a photo of that same spot from 100 years ago. The app's creator, E J Kalafarski aims for historic scenes that "illustrate particularly stark contrasts with today," and photographer Scott Lynch set out to recreate 15 of the shots.
