and before you'll scream 'that cannot be, that rectangle is too dark' - take a look at this:
en.wikipedia.org...
sometimes we see what we expect to see - because illusions are born in our minds, not in our eyes. you can't really trust your own eyes without
trying first to see more than it seems there is, because what you see always goes through your mind and what you think is a raw image, is in fact just
your perception of the reality. the more you can free your mind from common ways of thinking, the more you can see.
