Alrighty then. I know something about color theory. I even know some arcania, such as the fact that the X and Y coordinates of the XYZ color space are on the projective plane and that the XYZ color space contains non-existent colors. Let me be a bit pedantic about psychology, though: shawnc never really believed that the world was sepia-toned a hundred years ago. He was just expressing amazement due the "uncanny valley" of which you speak. I feel confident that he knew why he felt this way, and that he didn't really need an explanation for it. When he said "my brain is having a hard time", this should have been a dead give-away that it was not his rational mind that was having a hard time, but rather his unconscious mind that was rebelling and making this "wow" feeling conscious. If it had been his rational mind that was rebelling, he would have said, "I'm having a hard time", not "my brain is having a hard time". Or at least that's how I interpreted his comments. Your mileage apparently varies.
