A green screen is a
CRT with only green
phosphor, much like that found on older
oscilloscope tubes.
Use a green screen and you will be in some bizarre sort of hacker
nirvana. I don't know quite what it is about them... they're truly magical. Most green screens are coupled to display adapters that only do text and usually simple graphics, further making the use of a green screen a
Zen exercise.
Green screens are peace.
Green screens are power.
ASCII FOREVER!
