Brilliant App Reveals What Your Exact Location Looked Like in the Past

Many recent multimedia projects have tried to present a "then and now" look at different cities by mashing up current images of buildings and streetscapes with historical visuals like old film footage, Eighteenth Century paintings, or classic album covers. Now, an app called Pivot wants to do the same but in real time, offering an instant time portal right as you're walking down the street. Pivot, developed by Boston-based couple Asma Jaber and Sami Jitan, prompts you to raise your phone when you're at a "pivot" point—and that's when you'll see images and videos of what that place looked like decades or centuries ago.
