Blue Screen of Death (BSOD)

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.

Install it on your "friends" computer.
I'm sure they'll see the humour in it - eventually.
