The BWGen I have only adds visuals to those goggles that have led's in them. Did they come up with a new one that makes your screen flicker?
I wouldn't use it, because sitting in front of my comp. isn't my idea of comfy, and I put the laptop on the side with the earphones when I use it (which isn't very often, I haven't used mine in prob. + than 4 months.)
But whatever. Just make sure you're not epileptic. Strobing lights can send an epileptic into a seizure.
