It's a StereoPhotoMaker screenshot to get *.jps files out of squeezed left/right
images.
I use normally two different camera locations and the same camera look_at
definition.

I've never been able to do the "stick your nose on the screen and look 
at each image with a different eye" 3D images. Maybe there is a homemade 
solution using cardboard glasses?

No, no - it's not such a simple solution. *.jps is one of the two most used 3D
image formates.

The software generates a jps out of two left/right images.
On most 3D TV-sets you can watch such images with glasses used in cinemas.

Much more interesting are 3D images you can pin on a wall (lenticular ->
"Wackelbilder" in german). For excellent effects you have to generate 20 to 40
images. Because of this I've generated only one source for a lenticular poster
(31 single images).

Why did you "squeeze" the left/right images?

That is the way I've done it. You could have posted the JPS file you 
know. ;)

I spent a little while playing with stereograms when I got a 3d screne 
about a year ago.
The image below seems to change eyes depending on the viewer I use. :(

This image is cross eyed and I can view it bare eyed.
If the viewer is expercting the roght image to on the left side, the 
perspective is OK.
If the viewer expect the right image to be on the right side, then the 
3D effect will be inverted.

What do you know? So can I but I have to reduce it to about 20% in size.

It is right image to the left but some of my software loads it right 
image to be on the right side.
I've not used the s/ware for over a year so I am rusty.

I absolutely cannot do it if each image is more than 6 cm wide.  It's a mystery
to me how anyone can.  Is there a significant portion of the population with
double-jointed eyes?

If I narrow the browser window to 12 cm, I can merge the images with some
effort, but most of the detail is lost.  I get more satisfying results by
switching the left and right images and crossing my eyes instead.  That way, I
can view the images at a large size without eye pain.

This mean that your eyes are about 6cm appart, or you have some strabism 
isue. For some other persons, it can be up to about 10cm appart.

You hit the limitation of parallel view: The image must be narower than 
the spacing between your eyes.
Now, it must be notted that eyes spacing can vary quite a bit from 
person to person, like around +-50%...
Why to you think the binoculars are articulated?
This mean that an image than can be viewed in parallel view easily by 
the author may be impossible to view by many other persons.
