k: re-discovery: bright green on black is painful in large
  amounts... but if you use a very dark green instead of black for
  the background, it becomes quite pleasant and continues to
  emulate the green screens.* I was lucky enough to work on them
  and surprisingly, you can sit at them for hours.* It's nearly
  impossible to completely emulate the glow and honestly, things
  look way better now - but every once in a while, it's good to
  shock the eyes I think :P
