You must have noticed the image in the greeting I posted yesterday. If you haven’t, then check out this screenshot and return back. I took it after waiting for several minutes on Twittervision yesterday.
Twittervision is a very interesting website that uses the Google Maps API and the public Twitter feed to show a real-time geographical visualization of tweets across the globe. It gives us a snapshot of what the world is doing at any given moment which can be zoomed down further by location. It has two views: classic and 3D. The former scrolls the map while the latter is a Flex app that scrolls all around the globe.
That said, for an app which has been used over a billion times in the two and a half years since its launch, I think there are very few tweets that are being displayed.
Twittervision has a Twittervision API that can be used by anybody to obtain the current location and status of any user (used for Twitter badges on blogs). Flickrvision is a sister application that is very similar except that it shows images being uploaded on Flickr.
This has been around for over a year and a half now but I am only starting to discover Twitter and apps centered around it. Dave Troy is the man behind Twittervision and has a very interesting blog.
