You don't know...
First off, I was referring to VL- Virtual Light, for those of you who don't read William Gibson (and you people call yourselves geeks? For shame!). Secondly, I get to fiddle around with these sorta technical toys a lot (no VR goggles yet, but I have little interest in current virtual reality anyhow- we've got all this nice ****, why go back to the colored-polygon days just to wear the stuff on yer face?). It's actually less the virtual reality bit than the fact that you've got monitor screens half an inch from your face- I know, I've worn non-VR video glasses and they gave me one ***** of a headache. Advanced screen technology sucks, with the possible exception of some of the things they do with LCDs.
