Web 2.0 - Twingly screensaver

This is possibly the best way to demonstrate the web 2.0 phenomenon.

PrimeLabs developed a screensaver application that depicts the blogosphere activity in real time! It's unfortunately not available for Mac users, but PC users are definitely going to have a blast.

The website also offers a video demo of how it works, if you want a preview before the download.
