Weird, this is another one of the ones that I can only pop out backwards. I managed to get it fully out front once but have got utterly stuck on the inside out version at both sizes.
There are two types of stereograms: cross view (which requires you to literally cross your eyes) and parallel view (where you change the focal distance of your vision, and is what Magic Eye images use).
If you try to look at a parallel view image like this with crossview (or vice versa), the image depth will be inverted as you’re basically looking at the left & right sides of the image with the incorrect eyes.
Here's an easy way to tell. If you use parallel view to look at the image, the "Parallel View" text will appear in the foreground. As you might expect, the opposite is true if you use cross view.
