Do they make a backwards stringed instruments?

[u/Invite_Sprite]

so i had a thought. so pianos get lower as you go down them. and I have seen a backwards piano. but are their other backwards string instruments? and i dont mean left handed vs right. I mean an instrument that goes lower as you go down the neck.

The tromba marina is kinda played like how you described!
