Not that your screen really needs saving these days, but some cruel jokers over at Microsoft TechNet have released the Blue Screen of Death Screen Saver for those of you with a sadistic streak.

The screen saver accurately emulates the dreaded OS hard crash that Windows is (in)famous for. It even displays accurate configuration information from your system to fool all but the most astute eye, and displays differently depending on the OS version you have installed. Perfect for that annoying coworker, or for a sentimental memory of a kinder, gentler time, you can download it for free here.
