i can't get that negative thing to work lol
I can and it's creepy.. I see skin tones and everything.. You have to stare really hard at the red dot though, and you need a really white surface to stare at.. I took the suggestion and opened a new tab on Firefox, so I had a nice white surface to stare at.
As for staring at the red dot, I stared without blinking until the entire image just kinda faded out, where you can tell you're looking at a face, but you can't really distinguish anything.
