Well, I've just seen a page on the Sysinternals page of the Microsoft TechNet, offering a Blue Screen of death screensaver.
One of the most feared colors in the NT world is blue. The infamous Blue Screen of Death (BSOD) will pop up on an NT system whenever something has gone terribly wrong. Bluescreen is a screen saver that not only authentically mimics a BSOD, but will simulate startup screens seen during a system boot.
• On NT 4.0 installations it simulates chkdsk of disk drives with errors!
• On Win2K and Windows 9x it presents the Win2K startup splash screen, complete with rotating progress band and progress control updates!
• On Windows XP and Windows Server 2003 it present the XP/Server 2003 startup splash screen with progress bar!
Use Bluescreen to amaze your friends and scare your enemies!
