Tweetping is an interesting project from
Franck Ernewein , which takes a stream of tweets from the Twitter public API and
places them on a map, counting the words and letters in tweets along the way, and displaying the last mention and hashtag.
Since it takes tweets from the public API, only about 1% of all generated tweets are shown on the map, but this is quite enough to draw a beautiful map.
UPD. You can make a cool screensaver out of this thing using
WebSaver (OS X) . Option for Windows (I have not tried it myself) -

Implemented on
Nodejs +
Socket.io ,
Processing.js and
Backbone.js .
