Stereograms

  1. Feb 29, 2004 #1
    Are you able to see the images of the stereograms? I've never and some times I think that that people are pulling my leg! I'm going to end cross-eyed trying to put the correct position of eyes! For example, are you able to see the image of this page?http://mathworld.wolfram.com/Stereogram.html

    It is very easy when you look at the center of the image and slowly cross your eyes, there will be a point where dimensions form, you should hold that position. Ofcourse you should have the ability to cross your eyes

    In this particular one I can't make out anything but a square and a line, and in the square I can see a tiger head and a snake.. but the last might just be my imagination :wink:

    I really envy your imagination

    I used to be pretty good at figuring out stereograms. However, looking at it on the computer screen seems to be a lot harder and I can only make out the word ERIC. Excuse my ignorance, but is that not the first-name of some math guy?

    I can see the word "ERIC" also, and a couple of squares/rectangles below.

    A tiger and a snake??

    I don't cross my eyes, I just allow them to "relax". An easy trick is to get close enough to the picture to touch your nose to it and then slowly move your face away from it, trying "not" to focus, you'll start to see an image emerge.

    This is a terrible stereogram, hard to make out. I used to love the "Magic Eye" books.

    I agree with Evo. This IS a terrible stereogram. I have always been able to just pop my stereo vision off and on at will. I never have to spend a lot of time adjusting. I more or less focus at a point beyond the page and, as Evo said, just relax. I posted links to a bunch of good ones in another thread not too long ago. If I can find them, I'll repost them here.

    I tried and tried, but I can't make out an 'eric' in there :frown:

    The letters are spaced E R I C, but hard to read. You're not missing anything, believe me. If you saw a tiger and a snake, you got a lot more out of it than I did!!!

    Eric is in the top half of the stereogram (I didn't notice it for a while); I'm not sure what's in the bottom half.

    There seems to be an offset problem with the image; I see what looks like it should probably be part of each letter, but it's off to the left.


    Also, I imagine everyone's screen has an effect on how well they can view it; try printing it, maybe it would be easier to view.

    Ah! Here are some of my favorites!

    I find it interesting that this one takes me a little longer to bring into focus than most others.

    And here is a VERY nice page with a pantload of images to choose from - with links to other pages!

    Have FUN! The more you view, the better you do! :wink:

    I think there are links (if not a quick google will do it) on some of the above pages about a viewing technique called 'parallel viewing'. This is how I learned to bring them into focus so fast and easy. It might work better for you than crossing your eyes (THAT can HURT! )

    Here is another fun one! (as you can see, I LIKE these!! )

    I like being able to actually move my eyes and look around the inside of the box when my vision clicks in. It's just too cool.

    I'm sure many of you have seen the works of M.C. Escher... I think he's VERY interesting!

    Here's a page with quite an extensive collection of his works:

    Yeah, that one’s really bad, sloppy job.
    I think I have sw for creating stereogram pictures somewhere on hard drive, or I had… anyway I copied it from guy who was using sw for cheating on exams :) he would print stereogram notebook cover (or something else he could put on desk during the exam) with tons of equations. But it’s boring and slow job, when you calculate you need less time for learning than for cheating this way (but u can’t say it’s not original).

    Gazing at a "Magic Eye" poster or book is less distracting and more centered. "Grams" are among the best visual highs I've ever experienced, natural or otherwise.
