Geocodearth is a screensaver that enables you to view tweets and Flickr photographs posted by your contacts from wherever in the world they uploaded the data. Once you've activated this screensaver, you'll see a three-dimensional globe that graphically displays where your Twitter and Flickr notifications are coming from. You can also interact directly with the screensaver, which means that you'll need to press the 'escape' button when you want to exit out of it. Geocodearth is an interesting app for anyone addicted to Twitter, since it allows you to follow what's happening even when your computer falls asleep.
