We use Instagram, and realize that a lot of other people do as well – but a new image aggregator makes it interestingly apparent just how many people globally upload photos to the app consistently. The site is simple – it aggregates all the images being taken in large global cities – Stockholm, New York, Sao Paulo – and updates a rolling feed to show what Instagrammers are snapping right at that moment. It’s an eye-opening glimpse of the depth of users, and an interesting collection of what they are seeing and sharing in their city.
