Anyone play?

that text one is good....didn't know it could be done like that...

gaping anus!

I find that staring wide-eyed at it and slightly out of focus while moving the screen backwards and forwards is a really good way to get people to think you're insane.

It also makes the pretty 3D pictures appear :)

We use these in Biochem all the time. these are the best of DNA I could find.
There are some awesome ones for proteins...

I've never been able to see these things either. Ever.

"The basic principle behind a stereogram depends on the ability for a person to merge multiple objects into one. There are many factors that could inhibit a person's ability to see the object hidden beneath the initial surface. As an example....place your thumbs and index fingers together in the shape of a triangle, and find an object in the distance to look at through the triangle. It must be a distant object! independently close one eye, then the other....you will notice that you were only able to see the complete object through one eye without moving the triangle. This concept is called eye dominance. Sometimes the brain will shut off one eye, and rely on the dominant eye, if the object to be viewed doesn't come in focus. There are many people who need corrected vision that don't realize it because of the human ability to adapt.

Another possible cause is convergence. At close range (12-18 inches), your eyes converge an average of 3mm...but this is not so for everyone. Just as you have a dominant eye for distance, you will also have a dominant eye for near. After years of depending on one eye to do the majority of the work, you can depend less on convergence and adaptability. By allowing your eyes to relax, and blur....you attempt to overide your brain's intent, and allow both eyes to be equally dysfunctional. Thus, images begin to overlap and the muscles that control your eyes are less likely to fix at the same point that they normally would. The same people that have problems crossing their eyes...even a little...will have the greatest frustration when attempting to view stereograms.

Other conditions such as esophoria and esotropia can cause the eye to move inwards...(commonly called a lazy eye), and exophoria and exotropia (a tendency for an eye to shift toward the temple), will have an impact. I would suggest that people could adjust their distance from the stereogram and have a greater rate of success. A distance that works for the majority, doesn't always work for everyone. And last but not least...I would enjoy the statistics relating the ability of a person to see stereograms with regard to their profession. Analytical/Artistic mindset?"

Can't focus on these ones for some reason. I can see it, in the way you start to see a stereogram and it suddenly comes into focus, but it never takes that step where it gets sharp.

I get the feeling I look like a prick trying to do this...

The same for me. Once I worked out why I wouldn't be able to see them I spent a lot of time bluffing other people into saying that they saw more things than they really did. I invented details, the idea of double stereograms, pictures which changed dramatically when viewed upside down or across a different plane and my favourite, the oscilostereogram which changed when tilted (like those leaping tiger action pictures).

I can't see them at all...but I'm also a colour blind loser.

sure we've been through it before on this fora..

i love these; i just blur my eyes, then slowly refocus, it's so easy, having said that, i prefer the dinosaur ones from the past to the one above.

i take any two shapes and pull them together and lock them as one shape, interesting hearing why people can not see them

I want more. That last one those looks kinda naughty. And also like a Smeear cap's fabric
