title: Make entire screen monochrome and other full screen effects
body: <p>Does anyone know how to apply effects to the entire screen, in c# or any programming language.
  I'm mostly interested in making the screen monochrome (specifically green-white instead of black white).</p>
  
  <p>I know a cross-graphic card solution is possible because I found a program that can do it:

  <p>Anyone knows how to accomplish something this or where to look?</p>
  
  <p>Thanks !!</p>
