Stereoscopic Anonymous
How I do the crosseye thing. First of all: if nothing else works for you, sorry... it's really hard to explain how to look at stereoscopic things properly.
The two things that matter are Focus (what you are looking at with your eyes) and Distance (how far away you are from your screen) note that I wear glasses, so you may have to adjust nearer or further, it varies from anon to anon.
1. Practice crossing your eyes and not focusing on anything. Cross your eyes and glance around the room, looking in general directions and noting that your eyes aren't focusing on anything in particular. 2. Find a small stereoscopic image to practice on. The second image in this topic is a good example, something under 900px wide. 3. Fullscreen the image (or view it at its full size. If possible, try not to have too much interference on either side of the image (ads or other windows or stuff). 4. Measure a foot and a half away from your screen. Move your head there, and cross your eyes, don't focus. Now slowly move your head forward, let them focus on the picture if you feel your eyes trying to move a little (don't let them uncross). 5. Now that your eyes are cross-eyed and focused on the image, move your head forward or backward until you can see it without straining yourself.
The rest is up to you. For wide images (1400+) I usually have to back up 2.5 to 3 feet. When you get the hang of it, it becomes as simple as crossing your eyes and letting them focus on the image, with little effort on your part.
Scaled images (or ones that are particularly pixely) are not very good to practice on.
Some people focus on the image (and see it crosseyed) but they lose it too easily. Once you have focus, wait and don't look at any part of the image for a few seconds. Slowly shift your focus across the image, skipping around can destroy your concentration and uncross your yes.
Good luck
