Dan's Data was talking about lasers and how they have to have all this battery sapping crap to make it green.
Apparantly it starts off with a UV laser that's just off the color spectrum. Then they add a filter that moves it even farther off the spectrum... Finally they add a 2nd filter that moves it very close to the wavelength the eye is most sensitive to. Was saying if you really wanted to, you could take a green laser and remove the filters so you could burn people's eyes
Simple version of what he was sayin, if I understood correctly!
