One of the most feared colors in the Windows world is blue. The infamous Blue Screen of Death (BSOD) will pop up on a system whenever something has gone terribly wrong. BlueScreen is a screensaver that not only authentically mimics a BSOD, but will simulate start-up screens seen during a system boot, making it great for playing pranks on people.
Bluescreen cycles between different Blue Screens and simulated boots every 15 seconds or so. Virtually all the information shown on Bluescreen's BSOD and system start screen is obtained from your system configuration - its accuracy will fool even the most advanced NT systems developers.
