re: the video
I did not see the gorilla, I was concentrating too hard at counting passes. However I remember being aware of something being anomalous during the video. I think this is where I missed two of the passes. I got 13 out of 15. NT or AS, I simply cannot get my brain to do two things at once. During the time I was feeling something wasn't right, my brain just sort of lost it's place for a moment or two and it was just like static.
