Wow. After you see it the first time, you can hold the color "in your mind" the 2nd time and slowly perceive what I guess is an after image "fading" (otherwise I tend to refocus too quickly). Rods and cones! If your pupils and time sense were severely dilated, I bet the effect would seem to take a forever ;)
A little while ago I heard 5-10% of your rods are predictive, ie, they will fire in advance of a regularly moving object, which is part of what enables you to catch a ball and shoot pidgeons. Hopefully someone out there has a good illusion playing on that...
that reminds me of

I've always liked the moon, actually... it appears bigger on the horizon, but isn't. But the thing that really gets me is that if you take a picture of a 'bigger' moon sitting on a horizon with a camera, the moon will look 'smaller' / 'normal' in the photo.
ಠ_ಠ, that is a pretty cool illusion.
How about this one?
This one's pretty good, but you have to adjust your eyes in order to see the animation.
I could not get this one to work at all for me, but maybe it is based on the fact that the center of your eye is blind*. Five minutes and I feel like a sucker. Nothing. Where is the shark???
* close one eye, hold your thumb straight in front of you, and move it very slowly back and forth horizontally but *do not follow it*, keep your eye still and relaxed. There is a very distinct point (maybe 6-8" from center toward the outside, and 1-2" wide) where your thumb "disappears" because it is in the blind area. It is not "out of focus", if you concentrate you can see part of your hand is simply not in the picture. Gone. I showed everybody I met this for a week after it was shown to me; I could just not believe I had been walking around the whole time blind in the center of my eye like everyone else :p
[edit, okay I think I found it -- more like a killer whale, and facing left?]
Interesting. I've never noticed that effect before. I know that some can't see stereograms due to certain visual impairments, but quite often they just don't understand the technique. Do you wear glasses?
>> I think I found it tho -- facing left and sort of waggling?
That's it. Once you latch onto it, relax your eyes, and the animation just sort of pops out at you.
I think this page is interesting:

Interesting. It's definitely turning clockwise for me - but then the position of the body even indicates that. Does anyone here really see it going counter-clockwise?
EDIT: OK, I did get it going the other way now, but the natural tendency is definitely clockwise, for me.
