New version here.
The stuff comes from here
IMPORTANT : Set your monitor's color depth to at least 24 bits. Otherwise, the illusions won't work as they're supposed to.Illusion 1 : You all know that monitors cannot display real cyan. Well, this illusion lets you see it. REAL cyan. Stare at the white dot, and a a certain point (you'll know when) a kind of blurry cyan circle will appear. For comparison pruposes, I've put a gradient on the right, and you'll see, the real cyan, the one you've seen, isn't there !Illusion 2 : Stare at the red dot on the left pic. When you feel like the red dot is vanishing, look at the piccy on the right. Ooooohhh creepy...The rest of the illusions are explained in the flash animation itself.Don't forget, LOOK AROUND YOU after you've seen the animated ones.
Oh, there's never the right category for my flash animations...
