i dunno

Is this a REAL optical illusion or some kind of computer trick? I stared at the damn thing long enough to hypnotize myself and I still can't figure it out. I KNOW that eyes can play tricks on you, because I've worn beer-goggles before.

That one is either really good or really well-programmed.


That is just fucking weird!

Its for real. Stare straight at the center and eventually you see a moving green dot amongst the pink ones. After awhile, all you see is a green dot and nothing else. Its not a computer trick. Its your mind playing tricks on you.

Yep, he explains it all at the bottom. Interesting site. He's got lots of illusions and explains most of them. It looks like a site you can spend a lot of time exploriing.

OMG I agree with Assrot! I have to go boil my eyes now!

Didja ever do any work on a computer with the old style green CRT? Sit in front of one of those for a couple of hours and when you get up, the room will look pinkish. Same sort of eye-mind substitution going on, I'd guess.

Uh-oh, did anybody else see a frog, or am I having flashbacks again...?

I saw a Vietnamese woman selling fruit.

What was the question, again?

It's real. After all the purple dots dissapear if you move your eyes or blink they come back. Computer has no way of telling that.

Doesn't work for me, the pink dots always come back.

Apparently living in New York has turned my eyes into sensitive bullshit detectors.

I saw the green circle with the purple dots. Reminded me of a bikini I saw one time on Clearwater Beach. Little purple dots moving around on a green circle. I was sober at the time!

If you like this kind of stuff, check out - you'll be amazed! Just go through the archives, all kinds of experiments, videos - why you can even work a cam corder over the bay in Melbourne, Australia, zoom in on people walking the streets...

After looking at the thing for a few seconds, I looked at blank space on my screen and there was a circle of greenish dots -- where there was no animation to simulate them, and of course no way the programmer could predict where on the blank space I was going to look. When I moved my eyes the (now fading) circle of green dots moved with them.

Posted by: McGehee on June 14, 2005 08:52 PM

Oh holy hell it worked! The whole circle disappeared for me and all I saw was a green dot going in circles.

Yup - it works! Pretty weird, for sure.

I wonder if this relates to the 3-d pictures? I have a couple, and my eyes kind of slip into that mode, you can almost feel it happen.

Worked for me. Very cool illusion.

Before they disappear completely, I get "partial sweeps" where only three or four pink dots will vanish for one sweep, then reappear in the next sweep. It all sort of wavers. It's hard to keep hold at this level...

Then, suddenly there's a sweep where they all disappear. This is very easy to "keep hold of". I have to move backwards or forwards, or deliberately readjust my eyes.

This is cool. I was never able to get those Magic Eye things to work, because my 3-D vision is crappy.

Strider - I have a trick for viewing the Magic Eye thingies... use reflections. If you are looking at a 3-D image which has glass over it, move off to one side or the other and locate an object behind you that you see reflected in the glass. Focus on the reflection - not on the picture ... after some time you should see the image of the 3-D pic come into focus. This never fails me!

Ever see the blue dot after you had your picture taken with as flash and you're sitting in total darkness? This is something like that.

Or, better yet, go inside a lit room after spending time outside on a sunny day in the middle of winter where the ground is covered with snow? When you go back indoors the interior of the room has a greenish or pinkish hue.

Wild Stuff!
