Just wanted to throw something interesting in there, which is lateral inhibition [1] Lateral inhibition in vision is basically a rod cell, which is sending a strong bright signal to the brain, inhibits the signal of rod cells near it, which makes them send a darker signal; it increases sharpness and contrast in lines and helps with edge detection before the brain ever gets ahold of the image. The wikipedia article has a graduated series of black to white stripes that demonstrates the idea. It looks like the stripes fade from light to dark. I bring it up because you can suppress this by covering the two sides of the stripe, providing a constant signal to your rod cells. I haven't seen the movie, but it sounds like (from the comments I read below) that might be part of what's going on. Using optical tricks to suppress certain pre processing the brain/eyes do. (this is more a post about how interesting lateral inhibition is, because of information being preprocessed even before your brain mangles it, than to disagree with anything you said, which is a really interesting idea as well) [1] http://en.wikipedia.org/wiki/Lateral_inhibition#Visual_inhibition http://en.wikipedia.org/wiki/Lateral_inhibition#Visual_inhib...
