World 24h is a pretty mind boggling project, basically a world map that goes and grabs photo’s from flickr and displays thumbnails of photos that have been taken in different parts of the world at different times with Nokia Nseries phones (or multimedia computers as they are called now). There is even a 24 hour slider at the bottom of the page in 1 hour increments that allows you to find pictures taken at different times of the day. The photos are grabbed based upon metadata and tags, essentially if you have one of these devices you just need to tag your photo with the nearest city, or alternatively Geotag your photo.
