Optical Illusion

[W1RKW]

 Note to the board moderators: If you think this should be yanked by all means do so.

A friend of mine sent me this because he knows I like optical illusions.  This particular illusion I thought was very different from the rest I've seen in the past.  I don't know if it is actually an illusion or some sort of web trickery. Nonetheless, I found it interesting and thought I'd share it.

If your eyes follow the movement of the rotating pink dot, you will only see one color, pink.

If you stare at the the black + in the center, the moving dot turns to green.

Now, concentrate on the black + in the center of the picture. After a short period of time, all the pink dots will slowly disappear, and you will only see a green dot rotating.

Nope, it is definately an illusion. I downloaded the image and dissected it and I could find no frame with a green dot. All the dots are purple so the green one is definately your eyes tricking you.  And the dissapearing dots, same deal there is nothing in the image that I could find that would make any or all of the dots dissapear for any time interval, so apparently the dissapearing act is also a eye-brain illusion too.  Pretty groovy and far out stuff.

This works on the optic nerve of the eye. I remember reading a Time/Life Science book from 1969 that show an American flag with yellow, lite green and black stars. The idea was to stare at it for a period of time than look at a sheet of white paper. You would see the image of the flag on the paper but only this time it was in the red, white and blue colors. Fooled the brain again! Its neat how the mind works.

I recently saw the same thing on some web site, except the flag was a Union Jack. 

Notice the circle with the pink dots, if you look away from them even after looking at it for only a second or so, you see a circular pattern of green dots.  So if the pink dots disappear even briefly, you will see the green image.

I looked at the black X for up to a couple of minutes, but the pink dots never went away.

Here's another one...

No wonder it's so hard to proofread and not still miss a typo.

I noticed that if you make the entire page go up and down really fast, everything is a blur. 

[Ed Nesselroad]

Old time newspaper types taught newbies to proofread by reading backwards...end of copy to beginning.  That way the brain is less likely to fool itself by "correcting" mistakes.  It's more tedious until you get the knack but much more accurate.  Something a ham might appreciate...like copying behind.

Two words: negative feedback.

Try it with a profile picture of Timtron. Stare at it for about five or six seconds, then look suddenly at a white piece of paper, and sure enough: there's Barry White with a gray beard.

Better check your optic lobe for a bad cathode resistor, Don!

The monitor on my first computer was monochromatic--specifically GREEN.  After working on it for a while, I noticed that everything I looked at away from the screen was pink.  Same phenomenon in reverse.  A physiological psychologist friend of mine said that was because red asnd green are complementary colors.  And here I thought they were Christmas colors!

Herb,
 I understand those colors are very popular in San Fransico......Lee
