distraction for the day: anyone fancy suggesting me symbology associated with changelings?

because as far as I can tell from a very cursory search my best bet is "stylised depictions of standing stones" and that's not quite what I'm after, so, you know.

(I am also toying with Symbology Around Metamorphosis, for which chrysalises and pupae seem like the obvious way to go for me for a variety of reasons, but I'm also curious about specifically changelings.)
