I think my little ditty (to the tune of "That’s Amoré") describes a moiré pattern quite well. As far as I know, this is the only joke that explains itself.
Here is another example (cf. Give Peas a Chance and Brush with Death) of finding someone else having done the same thing. A friend showed me a book, by humorist Spider Robinson, which contains tons of other variations on "That's Amoré;" all puns on amoré homonyms. At least one of them was one I had planned to do in the future. I guess I've been freed up from that one.
