is a prank screen saver that authentically mimics a dreaded Windows NT "Blue Screen of Death". 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 the blue screen seen during a system boot, complete with a fake CHKDSK of disk drives with errors. It 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 advanced NT developers.
