A genuine ASCII stereogram!
David B. Thomas
To get the 3d effect, you need to diverge (unfocus) your eyes
such that two adjacent letters in the same row come together.
To help you focus, try to make the two capital O's at the top
look like three. Once you've done that, the rest of the image
should jump out of the screen at you!

Yes I did. But I also noticed that I could make 'near' appear behind 'far'
depending on how I focused my eyes.

Well, in fact, I can't see it any other way- near *is* farther away than
far. Just look a the codes- the "far"s are widely separated meaning
they're up close, while the "near"s are closer together meaning they're
farther away...

I found that the odd rows appear closer if I fuse two adjacent letters.
If I fuse 2 letters 2 columns apart, then the even rows appear closer.
So fusing letters at odd or even distances give the opposite illusion.

nice, but I found a nice *REAL* random-letter stereogram, a while
ago. It was posted by charles durst to the "3d" mailing list
(see mail headers below for info). There is talk that this list
and this newsgroup will be gatewayed sometime soon. anyway, enjoy
the following. --kcb

With all the talk on this list about "random dot stereograms", I have
been toying with the idea of writing a program to generate random LETTER
stereograms. The only problem is that I don't have enough spare time to
write such a program.
Anyway, I just created (manually) a sort of "proof of concept" sample of
what I'm talking about.
It is intended for cross-eyed free viewing. Cross your eyes until the
V's and X's at the top and bottom overlap with the adjacent ones.

The letters are not really random, I just got them by pounding on the
keyboard with CAPS LOCK on. Since there are far fewer letters than there
are dot patterns, it seems to be very important to avoid repeated letters.

Absolutely! This is the BEST 3D experience I've ever had with one of these.
The O's REALLY helped me. I found that once I got them lined up, not only
did the rest of the image POP into place, but I could then divert my attention
throughout the rest of the image without losing the effect. A first for me.
Definitely a great image to practice learning this technique on.
Thanks.

I couldn't figure out how to a random one... I know that you have to shift
things by one to make it appear at a different depth, but could someone
give a simple algrithm to do this:
Given: a mask:
##### #####
return a row:
v v v
ABGHDPLOQMENERUABGHDPLOQMENERUABGHDPLOQMENERUABGHDPLOQMENERU
(only shifted correctly...)
I would think you would do a row something like this:
v v v
ABGHDPLOQMENERUABGHDPLQMENEORUAGHDPLBOQMENERUABGHDPLOQMENERU
^^^^^ ^^^^^
Note the two places where I shifted...
Is this correct? This seems to be different way from the random stereogram
that was posted just recently.

I found that if I crossed my eyes I get a different effect from when
I unfocused my eyes.
My 2 cents,
Richard.

Yes I did, thank you very much. So much so, that I have created
one of my own. The instructions are as before:

Try moving your head back from the screen and moving it about a bit
once you have focused on the image to increase the stereo effect even
more. Have fun! Perhaps we can have a whole series of these!
