Your two panels here are the same image side by side (whereas the cut out center panel was mirrored). This gives an illusion of depth because of the position that your eyes are relative to the rest of your surroundings, on top of some visual artifacting created from copying or exporting as a gif. For my gif you should only see 4 panels total while crossed, including periphery. It is pretty tricky to see

edit: To clarify I recommend thinking of this GIF as data visualization in a stereoscopic medium, where the depth illusion is created by reflected symmetry, and not the usual parallax stereograph, where two pictures are taken of the same object from slightly different angles. Stereographs usually use parallax, but not always, sorry for the confusion!

You are correct that this is reversed/mirrored in the center. I have 3 panels so that both cross-eye and uncross-eye are visible at one time. There should be 4 panels total when crossed correctly, two opaque in the middle and two "see through" panels in the periphery on either side. It is tricky to see for sure.

The reasons why I mirror these have to do with symmetry of lensing, where the same image appears on opposite sides of the lens with black holes, as well as the mirroring effect with strong gravitational lensing, where galaxies can be seen as mirrored smears, sometimes multiple times.

Years ago I fantasized about Earth Space Station about the size of Montana floating up there. I had 5 space ports feeding shuttles up to the space station: Djibouti was one of the locations for the shuttles because of the kindness and sensitivity of the people... Now I can continue my story!
