Oh the whole article wasn't about dish. It was just Hd in general. Apperantly the human eye only sees so many things, and it shutters a bunch of times per second, to build a completed picture in our head, based on what we assume it to be. It was neat some of the tests it asks you to do on your own. I saw similar things in the show Brain Games, but this was more in depth. If I get done with my college work, I'll take the time through the forum and see if I can find it to repost. It was grossly off topic then what was being discussed, but a neat tidbit for the question just a few posts up. It sort of tied in with Scott's comment in a round about way.
