I have a half-face mask along those lines made for me by an ex-girlfriend. Sadly, she was not a mathematician, so the specific formulae aren’t of much interest. Nice to have for the occasional costumed ball, though.
I met a bloke once who had Euclid’s proof of Pythagoras’ theorem tattooed on his arm, and got into a drunken argument with him about whether or not he should have chosen a more elegant proof.
