The Cool/Rare/Weird Instrument Appreciation Thread

[Frownland]

Post instruments that you think are interesting, preferably ones that are kind of uncommon. Expecting to see a lot of great stuff here. I'll get the ball rolling with

Umrhubhe

The mouth acts as a resonator where you can change the overtones of the bowing, making a whistling sound. It originated with hunters using their bows as instruments before it took off throughout various tribes.

The Fluid Piano

Great for ragas and other styles of music that uses microtones.

Viola Organistra

One of the more infamous unique instruments since it was invented by Leonardo Da Vinci, but wasn't built until long after his death. It uses the organistrum design (better known as a hurdy gurdy) and applies it to the piano, with the foot pedal controlling the "bows". I have wet dreams about the drone music that this one can make, I find the classical approach in this video to be a little sterile tbh.
