It's not you so much as the stereogram. This one just isn't that good. I can get it with no problems but I tend to search for stereograms on the net. BTW: some are parallel and some are cross-eyed. That is, they are made differently. This one can be viewed by gluing your eyes to the page and slowly backing away from the image while not shifting your focus. That's a bit of cheating but should work.
