Worldcam uses Foursquare and Instagram API to show photos from specific locations!
Foursquare and Instagram are both immensely popular mobile apps. Combine the two and you can easily find photos of popular locations around the world.
Worldcam is one such project which aims to make it easy to locate Instagram photos from select location.
The service lets you search for a place and would show Instagram photos tagged at that location.
You can even use it to find photos taken inside restaurants and museums! Cool project.
