A new service called This is Now lets you see the world through Instagram's eyes. All you have to do is pick one of five major cities (New York, Sao Paolo, London, Tokyo, or Sydney), and you're instantly immersed in a beautiful real-time visualization of Instagram photos from those locations. Once you start watching, it's hard to pull yourself away.
The This is Now project is a visual composition which uses real-time updates from the ever popular Instagram application based on users' geotag locations. The tool streams photos instantly as soon as they are uploaded on Instagram and captures a city's movement, in a fluid story.
