Fascinating twitter visualization. It's scanning tweetfeeds for the phrase "Just landed in..." or "Just arrived in..." and tracks the location the Tweet was sent from.
The user's original location is found from their profile and an airplane flight path pops up on the 3D map of the world.
Looks pretty clear in which country people are using the twitter the most : USA is on the 1st place, Europe comes after. Might be useful for the News companies.
