Yes, the previous commenter just specified that the image should be seen “wide-eyed” (eyes focused on farther away / closer to parallel) than Cross-eyed (eyes aligned like you were looking at something closer).
If you go cross-eyed, the depth is reversed/incorrect since you are seeing the different images with the wrong eye.

Are these before and after? If so that looks like what I would expect fire to do to granite.
It’s a stereoscopic photo; if you cross your eyes when looking at it so that the two images overlap, it will appears 3D
I tried it cross-eyed but the perspective is wrong. I think it’s wide-eyed like a viewmaster

It’s tough but doable without the guide dots.
