If the computers are like ours and have a screen saver at the logic screen, (We use XP but we have the dialog box) then you can walk around and press power on them while they have the screen saver-they'll go back to the "Press CTRL+ALT+DEL" box, and then when they do it shuts down instead.

Or you can just press ctrl+alt+down to flip the screens upside-down. Then flip the monitors upside down so the screen is the right side up. Or for you programmers, make a prograom (hidden with FreeConsole) to run on startup that does it every minute-in a random direction.
