Lifesaver is a new Gnome Screensaver that searches Twitter & Indenti.ca for mentions about Ubuntu, then displays them on your screen.
Useful? Probably not. Geektastic? HELL YES.
Sadly it only currently works in Karmic due to package deficiencies, but since Karmic is only just over a month away – bookmark it now for installation later!
If you’re already rocking the Karmic Koaster, you can install it from the official PPA @ https://launchpad.net/~cmsj/+archive/lifesaver
