ScreenOff

ScreenOff is a "boss screen". When run, it blanks the screen, so that it appears turned off, and it exits if you click the mouse. A good idea would be to Create a shortcut to it, assign a HotKey to the shortcut, and stick a piece of painted scotch tape on the screen LED. That way, when you activate ScreenOff, nobody will be able to tell it`s on, so stop turning the Monitor On and off all the time when the boss comes in just to show that you are working instead of playing solitaire
