What's better than a Dashboard widget that can display a Mac OS X kernel panic? A full-on screensaver that can simulate one, of course! Mark Johns of Doomlaser has built an eerily realistic kernel panic screensaver, right down to the slowly dropping grey shade of despair, that will surely induce panic in the hearts of its victims in the way that only the haunting question of "oh crap, did I save?!" can. For a nice touch of style, it can even pause iTunes to really stop the show.
Watch a demo of the screensaver here in this post, or head over to YouTube for the original. Finally, you can snag your own pranktastic copy from Doomlaser.
