I'm confused? Don't they all require crossing your eyes? I've gone through about 20 on this site and "solved" them by crossing my eyes and locking the patterns

  Most of autostereograms are meant to be seen wall-eyed, instead of cross-eyed [0]. With wall-eye, you shift the convergent point being what you're seeing, while with cross-eye you shift it before. So it creates the exact opposite 3d. Watching a stereogram meant to be seeing wall-eyed, cross-eyeing you'll see an upside down 3d. Some stereogram are mean to be seen cross-eyed though, which is considered easier to see. [0]: https://en.wikipedia.org/wiki/Autostereogram https://en.wikipedia.org/wiki/Autostereogram

    It wont’t turn the image upside down, but the depth will be inverted, so what is meant to jut out at you will become a trough away from you.

      "the depth will be inverted" better describes it indeed. Thanks clarifying it!
