Basically, a 2000s webcomic about gamer culture devoted a comic (titled Loss) to the writer's partner who had a miscarriage. It's four wordless panels, and the characters in each panel take up roughly the positions of the rectangles in the OP.
Tonally, it was the complete opposite of what the webcomic normally covered, and it really shocked its readers who, being an internet community, responded with irony and parody, and now there are a ton of Loss references out there.
Only the transformations one is correct. All the other ones seemingly also preform a translation, and even if they might be correct if you take the orgin to be slightly outside of the shape but that's bad for educational purposes. Also this one makes the translation transformation look like the identity transformation.
This last one might just be me, but shouldn't shearing be included here?
