blackscreen is a QT application which does more then nothing. When you start it, it just shows a black fullscreen window (and hides the mouse pointer).
It's meant to use for presentations. If you want to turn your projector off during a presentation (maybe to write something on the board), you just start this application and later press "Space" to get back to your transparency.
