I'm a Mac user. If I want to see a proper and authentic Blue Screen of Death, all I have to do is fire up Windows XP in a Parallels virtual machine and run this handy screen saver. If I get tired of watching, I can just click over to one of my other desktops (via an extra button on my Logitech mouse) and get to work.
Fantastic! Leave it to SysInternals to come up with the Official Microsoft BSOD Screen Saver!
