This is Now offers a real-time glimpse of life in cities around the world as seen by Instagram users.
The site pulls updates from photo sharing service Instagram and uses the image geo data to cull images by city. This is Now then streams photos as they’re uploaded, creating a photomosaic of each city. There are five cities represented at the moment — New York, Sydney, London, Tokyo and São Paulo.
If you’d like to see more images from a particular person, each photo links back to the photographer’s Instagram profile.
[Update: If you like This is Now, you may also like Fourist. Fourist is a similar project — aggregating Instagram photos by city — but focuses on photos from the weekend so you can peek in on what the rest of the world does on the weekend.
