I agree, a very convincing demonstration of the fact that our senses aren't so much "recording realitity and absolutes" as "determining relevance and realitives". Another interesting example of the same principle (tactile, not visual) goes like this: You need 3 cups of water. One with rather hot (say, 45 C) water, one with cold (below 5 C) and one with room temperature (20 C). Now, put your left index finger in the hot water and the right in the cold one (or vice-versa, and use any finger you like etc.). Hold them there for about a minute or so. Then put the fingers in the cup with the room-temperature water. Now, tell me, can you trust your senses? I won't lecture on this, not the right place :) but the psychological implications are in fact immense, as the principle also applies to the way we interpret reality, depending of our past experiences and our present state of mind. You cannot trust your own judgements :)
Thanks again for this glorious link!
