Carp-pet & Moire Illusion
Moiré patterns are usually annoying. But they have a certain commercial appeal. It would be interesting to actually track the emergence of products like this one. I'm sure that magic lanterns, optical puzzles, and logic puzzles have a long history. But I'm not aware of any historical literature that has actually examined the ways in which cultural products commercialized and thus promulgated scientific knowledge.
