That is awseom YeahhH!
Makes my eyes go funny... man thats weird..

For me the pinks go out in order then come back on after another round of the green, cycling like that.

Got anymore?

This is a very cool illusion. Very david copperfield ish.

its the background, change it to royal blue for example the dot color will change when you focus on the black +

that's some cool stuff man - ooh *does it again*

when i focus on the + the pink dots dissapears

Well thanks for the info!

It's amazing how easily human eyes can be tricked just because they are focusing on a certain thing. Crazy...

wow thats amazing, i looked up a bunch more on this site -- http://www.michaelbach.de/ot/

owww burns my eyes.......i shouldn't be staring at thast with epilepsy....oh well *stares to make the pink dots go away because pink needs to dieeee*
I saw once this one thats just black spots on paper and in between you see flashing dots if you stare long enough...gonna have to find that

I have alway liked the unconstructable objects:

http://en.wikipedia.org/wiki/Optical_illusions

Paradox illusions offer objects that are paradoxical or impossible, such as the Penrose triangle or impossible staircases seen, for example, in the work of M. C. Escher. The triangle is an illusion dependent on a cognitive misunderstanding that adjacent edges must join. They occur as a byproduct of perceptual learning.

The color change illusions annoy the hell out of me. Why does the eye do that?! It's fascinating yeah but why why why???

Its actually quite simple. What you first must understand is our ability to make an accurate depection to ourselves of the world around us is learned, not innate. Images constructed in the mind are done so based on information received, and at times the mind will construct images based on only partial information. This is where the error occurs, and the mind is forced to make up for it. So it tries to match memory and stimulus to create and image. So it then chooses what seems to be most reasonable, and present that to your mind. Illusions like these one occur when the choices it makes are wrong.


Think of it this way, ever see a spotlight shine down on the ground, like a big one at a prison or perhaps some kind of club or large event? When the light shines down at the ground, you see it as it passes through the dirt and dust in the air, but more importantly, the spot it makes on the ground is your focus point, thus your able to determine the angle of the beam knowing the location of its source, and therefore in your mind at least, view the beam in its entirety. But when the beam is shined twards the sky, it appears to just dissapear into nothigness. The reason for this is not the lack of material for the light to pass over, there is still alot of dust and debris in the atmosphere, however now that there is no end point of the light for your mind to find, it can't create the angle, and thus see the beam. Your mind is looking for it to be straight, when actually the beam may be inverted even just a slight bit, thus causing your inability to see it. Your mind is once again constructing images based on partial information and your unable to see the beam. Its there, but the illusion is presented of it just disspearing.



Understand? ^_^

OO the grid! That's what I was talking about!

Actually, there is an art contest on FAC inspired by Escher that just started. I'm trying to decide what to base my picture on though....hmm....maybe I'll be predictable and do a phoenix fractal....
