The worst for me are the 3d spinning dancers where you have to try reeeeeeaaaallly hard to make it spin the other way.

Well.... yeah? I saw them instantly. And I can't see Magic Eye for shit no matter what (I'm still convinced those are a practical joke the whole world is playing on me).
I can't see them.

However, for magic eye, the wiki article helped me understand and see them.

It always helps me if I use my finger to point/spin in the direction I want it to turn.

Now that you mention it, I can see the circles. The trick is to follow the horizontal lines in between the squares. Then you can see the rest.

Magic Eye is real. I struggled a lot to see it (and still do), but it is possible! Do you notice how if you focus on something close to you, the objects in the distance get crossed? That's what Magic Eye exploits.
I find that if you focus on a reflection on your display, your eyes will cross the contents in the display since you're focused on the reflection. Then you have to scan over the image without losing focus until your eyes pick up a 3-dimensional figure in the image. The resulting image is usually a 3D shape wrapped in the background image, which isn't the most obvious thing to spot. But there will be a foreground and a background that looks kind of like the 3DS's 3D.

But I don't cross my eyes. I could never do those dumb 3D tricks where two identical images are put side by side. That has to be a joke.

so, for the Magic eye things, it's not that your eyes are crossing...your eyes are diverging.

This is one thing that quite often catches people out, in part because there are stereograms out there that are dependent on your eyes converging (i.e. focussing on a point in front of the page). Magic Eye branded ones, though, as you say, are based on diverging (i.e. focussing on a point behind the page)

I really struggled to get Magic Eye to work for the longest time, practiced it extensively one holiday, and now I can literally 'click' it on straight away, and can adjust my focal point mostly at will (I say mostly, because I find converging a bit uncomfortable, but can do it fine). For what it's worth the tip that worked for me was to bring the book close to my eyes (with guide dots at the top) until it was so close that getting the single unified dot was trivial, and then trying to hold that focus while moving the book away from me.

It's also a nice shortcut for spot the difference puzzles - if you can adjust your eyes so the two images for the spot the difference are fully overlaid on each other, you'll note the differences appear to 'flicker'. That tends to be quite hard, though, the amount of divergence required is quite high (compared to Magic Eye that tends to not expect you to shift the image more than an inch or so)

That tip worked. Prior to your post, I didn't know what people were talking about. The image looked like inset moulding you'd see on doors and nothing else. Didn't know where the circles were:

There's 16 circles in the picture.
 
None of these got me but fuck that dress. It was white and gold for three pages then all of a sudden I see it again and it's blue and black very obviously. I went back to page one convinced it was an edited image. To hell with that thing.

It still puzzles me.

Hint: Yellow = White - Blue
Also, note that the colors surrounding the image are conditioning your eye to see something that isn't there. Notice how on the right side there is a blue shade whereas on the left the dress is lit with a yellow light?


Proof: Take a paper plate and paint it into say 12 triangular slices, alternative with red and green colors (white = red + blue + green, so red + green = white - blue). Spin the plate rapidly. Your brain will interpret that as the color yellow.
 
I have never seen that dress as anything other than black and blue.

Also there is nothing in those goddamn magic eye pictures, you are goddamn liars there is no boat.

You're right about the red part, but not the gray part. From a quick test the pixels have less red than blue/green in them. White part of the berrys are cyan.

What I meant was that all the pixels that appear red are actually gray. Of course there is not just gray in the picture, as you can clearly see in the image I posted directly below the strawberry image.

In this thread we learn that a lot of people don't understand what an optical illusion is, and then get really angry when people see said illusion differently to them.

Pretty fucking much.

People arguing that they're right about the color of the dress, or people who don't understand how it "magically" changed colors, despite countless fucking posts explaining it, are objectively idiots.

I can finally do this now. I widen my eyes slightly then watch the outside leg and quickly scan across in the desired direction and it changes on demand. Pretty crazy stuff.

This thread is a perfect example why eye witness testimony or "I saw it with my own eyes" is meaningless.

Fun story from my younger years. I took a criminal law class in college taught by a guy who was a cop and a lawyer. One day during a normal lecture, the dean of our department came in, handed the professor something, they had a couple words, and she left.

About 30 minutes later the teacher interrupted himself, this time to ask us to write down everything we remembered about the encounter I described above. There was maybe 30 students in the class and I swear we had 30 different depictions of what happened. Some said the dean was angry, others that she was friendly. People remembered her handing different things to the prof. Some thought he said "Thanks hon" as she left, while others remember "Thank you ma'am," or "Thanks Sheila" or whatever else.

The variation was remarkable, and the professor pointed out that we were sitting relaxed in a comfortable surrounding, far away from the kind of stressful/scary situation where people are often called on to relay details to the police. Interesting stuff.

Holy shit. I was staring at this for ages with her spinning clockwise thinking you had to be trolling because there's no way it could spin the other way. Then out of nowhere she's spinning anti-clockwise and I can't make her spin clockwise again. Great stuff but my brain really hurts now.
Pretty fucking much.

To be fair, the dress is objectively blue and black. My wife owns it. Sure the black is a little goldish in the photo but that's just the camera. It's blue and black in real life:

Yes, that is agree upon that the dress is that color. But the colors in the image in the photo is not.

Very easy to check with paint programs.

The dress is black and blue and has always been black and blue. I have no idea how anyone gets white out of that. Gold I'll give you, since the black is super washed out and I could see it interpreted that way, but there's not a shred of white in that dress - none.
 
The dress was white and gold the first time I saw it and I would have fought anyone who said otherwise. I was looking at it in my computer, looked away for a few seconds and when I looked back it was blue and black. I stared at it for about 10 minutes just to make sure it wasn't a gif. Haven't been able to see it as white and gold since.
 
I love this one



Don't get it, the circles stood out very clearly to me

I had to have the circles pointed out to me clearly before I saw them. I just saw the multi-layered grid-type pattern that reminded me of the type of patterns found on doors like these.

One day I realized that sadness is just another word for not enough coffee.
I actually have to try to make that one "spin". She just goes from left to right and then right to left.

Who is brave enough to try the McCollough effect? An optical illusion that can last up to 3 months!
Yeah, I'm seeing the patterns all over the forums now hehe. It's weird. This will be interesting to see how my mind does with this because of my TBI.

if I look from the right end of the items, it is three. If I look at the left end, it's four.

The dress thing will forever baffle me. I have no idea how people can see anything but a midshade of blue and a slightly washed out black. Like there is no possible way in my mind for it to be anything else.
