Let me answer this way. What colour is the moving dot when you first see this and after a few seconds of staring at the middle. 😉
That's exactly the point, it takes learning to see what is really there.
If you run in circles you miss the detail. 😀
Persistence of periferal vision. Did you know that with a moving optical slit and distant bright point source of light you can examine your own retina and fovea?

It looks like green.
Anyone can be fooled, it's how our brains work. 😀

Anyone with real brains knows immediately that he has been fooled and in reality it's simply the background color. The same principles apply to audio. 😀

Not if it was a transient. You would simply think you saw green and that a green wavelength was physically present. It is not. And it is NOT the background color. It is the opposite color of the physically present dots.
This is my favorite visual illusion:

Asian women and tortoises? Huh? Where did that come from?
Sorry "asian women" have nothing to do with it. The two women singers conjured Mothra IIRC.
Turtles/Tortoises
Meanings derived from a turtle/tortoise motif are complex in Japanese culture. Hinduism, Taoism, Confucism, and Buddhism all contribute understanding. These traditions claim that the tortoise helps prop up the world, guards the northern quadrant of the universe with the snake, and carries on its carapace sacred inscriptions. The animal is believed to live to an exceptional age. According to Japanese folklore the tortoise then develops a flowing white tail and exhales special vapours that conjure up sacred jewels.
Primarily the tortoise is a symbol of longevity.

Does anyone have an upload of that Diana Deutch sound sheet that appeared in the AES journal?
I was being a bit tricky here. There are plenty of optical illusions. In comparison, there are far fewer audio illusions. That being said, the brain does a lot of self-organization of information, a lot of filtering. It is conceivable that there is some sort of implicit "learning" happening when listening to a certain sound system for a while.

While we are on about visual illusions and the way the brain works I once came across some amazing visual "trick" to do with the left and right side of the brain
An image (that's hardly the word) of random black and white blocks on a page... like large pixels. What you had to do was hold a mirror to your face, can't remember the exact details now... and view the paper image in one eye and the mirror image in the other and superimpose one on the other while looking in the mirror. Sounds bizzare I know.
Apparently your brain then starts making thousands of "calculations" and slowly you see a 3D image appear such as squares one in another fading into the distance. Once you have seen the image you can't ever believe you had to wait for it to appear.
It was many years ago... very impressive though

Scott.
I would also be very interested in that AES soundsheet.
Diana Deutch did have these audio illusions on CDs that could be ordered from her website.

I'm only trying to say that not everybody has enough brains in order to realize that he has been fooled by his own brains.
As for the color, see below:
Well I don't think your brain in this particular case is trying to fool you. Colors, Sounds, Smells all of these things should be considered a form of trickery or hallucinations or illusions if you were to be picky about these things. Because in reality all that exists are molecules and wavelengths and your brain assigns or generates the colors to these patterns in order for you to easily differentiate these things. And in some cases it is more important to contrast or differentiate things against a background than others. One would be if something was moving just outside your vision - it would be a very good survival tool to be able to perfectly contrast what is moving against what is stationary. Just a guess though.

So that's what EnABL is doing. 😛
Optical illusions are common enough that I don't know anyone who wouldn't understand the implication immediately. And I don't see how a hard-wired limitation of one sensory channel translates into the wish-fulfillment of another continually advanced here. Are you saying the green dots signify greenbacks and it's a status thing? Is a version available for Canadian currency? 😀Anyone with real brains knows immediately that he has been fooled and in reality it's simply the background color. The same principles apply to audio. 😀

Gamera Perhaps?
Gentlemen, isn't it all something like talking " about taste of goose's meat, which was fed by rotten fishes " ( M. Waltari: Sinuhet, the Egyptian )? Do you think, that the same problems about sound of cable have Muslim, when lead them to the megaphone on minaret? 😎
Cool illusion Iko! Had not seen that one before.
Just to point out, AFAIK, this is not the brain being fooled. It's the chemistry of the eye.
There was a great piece in Scientific American regarding this stuff about 10 years ago. I can't find the issue now.

I don't know and haven't looked into the exact mechanism. But after some time staring at the middle cross one should no longer see any of the pink dots and instead, just a moving green dot. 🙂
Going off topic now... but this is cool,

look at the silhouette

Every pre-teen fantasy realized. Keep that up and you'll summon GK. 🙂
It's all fun, sure, but the really, the initial claim was that out of two identical cables, one will sound differently after burn-in. If illusive perception was indeed involved, and no actual change happened in the cable, then should the illusion not apply to both cables just as well? We need the test done. One person, anywhere, with independent witnesses/controllers of the test. If the test is to be setup anywhere near my location I volunteer to help, out of curiousity.
