RSS Screen Saver
Another cool Tiger feature is the built-in RSS screen saver visualizer. You can take any RSS feed and load it into your screen saver and the blog entries will rotate into view, one after another, via a floating, virtual spiral staircase. O’Reilly has a nice write-up on how to configure it using the RSS feed of your choice. Give it a try with your own feed, of use one of ours: Laughing Squid or Squid List.
