New York City has transformed dramatically in the last century.

Andrew Farris, a photographer from Vancouver, documents this evolution by snapping photos in 2016 at spots that he's also found in archive photos. He then meshes the archive images with his photos to create mesmerizing GIFs.

Farris has shot photos in more than 25 cities around the world, including Glasgow, Berlin, and London. His newest series is photos from locations around New York City, like Times Square, the Brooklyn Bridge, and Flatiron.

"New York is unlike any other city in the world as it pioneered the science and engineering of skyscrapers over a century ago, and few cities anywhere else caught up until the mid to late 20th century," Farris says. "While preserving this heritage, the city has maintained its lead as a place for cutting edge design."
