CatherinetteRings, an Etsy seller from Montreal, made this music box that looks like a robotic spider. When wound, it plays "Frère Jacques." I think that taxidermed eye really sets it apart from other steampunk spider music boxes.

Steampunk does not have to be practical and need not obey the laws of physics. It just has to be overly complicated and made from materials available from 1850-1920.
