Cool concept. I didn't know this was possible without using some of that Magic Eye 3D trickery. So if you want to create one of these, taking 2 pics at 3 feet apart is the standard distance?
It didn't work for me. Then again, I wouldn't expect it to considering I'm like the guy in Mallrats who couldn't see the sailboat.
Try crossing your eyes until there is a new combined image between the originals. The new image will have more depth.
I can just hear my mother now, "Stop doing that! do you want your eyes to stay like that?"
The cross eyed method works well simple by taking to images. Line up your shot and lean to the left leg, snap. Lean to the right leg, snap. The minor visual differences in elevations and lighting will give the cross-eyed image depth.
Wonder how many ehMacer's will be staring cross-eyed at their monitors tonight.

Your last one was cool. I don't consciously cross my eyes, they simply unfocus and "find" the new image. A skill I picked up at cocktail parties, no doubt.

The last one was never intended to be stereo. Just took 2 different images with different zoom ratios and slightly different locations. Had to crop in quite a bit and crop each image by different amounts. A bit more separation would have been great but like I said I was just trying to get the best framing.
As for separation for close-ups 3-6 inches is often enough. For scenics it really depends on how close you are to the foreground. Any thing from 2-5 feet to several hundred feet. Since images can be 2 or 3 MP jpegs no reason not to shoot several and pick the 2 that work best together. After a several tries you will get a good feel for the correct separation.

Must be my eyes but I can't see anything but two separate, identical pics on any of these things and that is going back up to 12 feet on a 22 inch monitor.

Don some people just can't do it. Nothing at all wrong with them.
Best bet is a piece of card board held between the eyes at right angles to the screen. Idea being to force right eye to see only the right image and the left eye to view only the left. Close one eye then the other to see if the cardboard is the right size & in the right place. I would think 3-4 feet would be about the right distance.

I didn't set out to take a pair of images to turn them into a 3D image. It just happened that when I took a few pix of the scene moving around a bit, two consecutive images had enough parallax to create a 3D view. You need a red-blue 3D glasses to view this 3D image. Unfortunately the colours are muted with this approach. Well, there aren't too many colours in the scene to begin with so you won't miss much.
eMacMan, I can't seem to get the 3D effect using a pair of left-right images side-by-side like the way you have yours. I wonder why. Perhaps the scene is too busy?
Hardly a new idea. Stereo cameras have been around since prior to the US civil war and of course many of us still remember the Viewmasters. However you can do it with any still camera by taking a photo and then moving the camera to the right and taking another. Works best with square or vertical shots.
The two images are put together as below.
This image had a separation of about 3 feet. If there is no close foreground separation can be a lot greater, as much as 100 feet or more. Greater separation will exaggerate the stereo effect.
The idea is to view the left image with the left eye and the right image with the right eye. Depending on your screen resolution you may need to be three or four feet from your monitor. Reflections can make the images very difficult to view. If you can see the stereo pixel images this one should not give you any difficulty, but some people seem to be unable to do it all.
