My brain struggled a bit with the upside down crater..
Yeah I didn't notice it till after I posted, should have flipped that bottom image to make the joke work better, but it's lemmyshitpost so why bother.
I've never understood this picture. Is the joke that there is no optical illusion? I have never seen anything else than all of the plates being right side up.
It works for me. The shaded inside of the indent is interpreted as the shaded side of a hill.
I was convinced it was a gif and I was blinking during the transition until I read this
