A split violin was the impetus for this Naked Lunch-esque beetle violin, just presumably without the talking or hallucinatory wackiness. Jake’s Steampunk contraption features a carapace that opens and closes, as well as fully articulated legs, which can be positioned to wear on your back! Make your very own wearable steampunk violin musical instrument beetle backpack fashion plate (phew!) at instructables.
Available for purchase at etsy, though sadly you will not be making real ear-gouging polka music with this nor playing backup for Weird Al (are there other instances in life you might use an accordion? I have no idea!).
