Oh hey that's cool.  I did see only a green dot rotating after a while.  Although I thought something scary was gonna pop any minute, lol.

[crashwg]

That was friggin cool!  It's so wierd when all the purple dots dissapear and then just to make sure it's not a trick you quickly look over and they're there again. 

[HyperHautian]

Wow, that is a cool website!

[screaming]

That's a neat trick!

No matter how long I stared though I couldn't get ALL the purple dots to disappear.  There was always at least 3 or 4.  Maybe my eyes have ADD too?

*blinks*
They just all vanished at once! Surprised the heck out of me.

[jbox]

Did anyone else get a "Pac-Man" effect? I found that they disappeared in order as the green dot "ate them up". 

[Bones]

I had visions of a far away place lost in time.

Whoa! Some of them are awesome!!

Think someone got some ideas from my avatar though! (jk)

That's very, very cool. Where was stuff like this back when I was into drugs?

Very Cool!!

[missioncontrol]

wow.... nice one......

now my eyes hurt 

[Chris]

Okay, that's officially freaking wild.

For me, they faded, but didn't disappear, and just as I was getting ready to come back and say it didn't work.... POOF!  They were gone!

[SirPoonga]

mine didn't completely disappear.  They became very faint.

Ignore the green dot, or the violet dot that flickers.  Concentrate on the cross hairs.  It takes me about 4 cycles.  After they disappear I can widen and tighten my view on the cross hairs to control the transparency of the violet dots.

What, you have opticular implant that allow oyu to zoom?

No matter what I do I can't make them completely disappear.

No optical zoom, but practicing with that image, has improved my x-ray vision.

I'm not sure if this means anything.  My monitor is set at 1156x864 with 32 bit color.

I think it has everything to do with how steady your gaze is. If your eyes shaking or quiver in even the slightest way...they won't disappear completely. Relax and focus on the crosshairs....

The phenomenon occurs when your brain decides the attenion needs to be on the center of your focus, so it selectively drops out the peripheral dots. If your eyes move at all, then they get "reassigned" a certain level of importance, since they are perceived as moving again, and they reappear visually.

From a site on Troxler Fading:
"What our mind appears to be doing is maximizing efficiency. If we keep getting the same uninteresting signal, over and over again, eventually we just ignore it

[SirPoonga]

I have pretty sensitive eyes too.  I was staring without moving.  Alot of people are amazed at stuff I notice and can see.

[Jabba]

Hmmmm, very interesting, I tried it at home over a dial-up and never saw the green dot, although everything easily dissapeared after a few seconds. I just tired it now over high speed at work and now could see the grren dod rotating, So those of you who can't see the green dot, you're not crazy, just a slow connection is all....

LOL  No offense, but that's one of the funniest sentences I've heard in a long time.

[Franco]

Thats strange.

[quarterback]

I would have thought that after the animation/applet (or whatever it is) had loaded, then it would rotate at the same speed and give the same effect?

It does, it's just a 38k gif, nothing more.  Exactly the same no matter what kind of internet connection you have.

It only works for me if I lean in closer than my usual viewing distance.

A dude at my work refuses to believe me when I say there really isn't any green dot. He thinks it's all an elaborate trick of imagery. He sees the green dot instantly so he just thinks the magenta is changing color rather than disappearing.

Save the .gif, open it up in photoshop (or whatever) and discect it into individual still frames for him

[Dartful Dodger]

At first I thought it was a trick too, so I did the above.

I still didn't believe it so I resaved the animated gif out of Photoshop, just incase the image I downloaded wasn't the file that was on the website.

They only tell you that to convince you you are. Then when your gaurd is down because you're trying not to be too paranoid... SHKKT!
