I saw this guy on Facebook the other day playing Devil Went Down to Georgia on an acoustic guitar against a washing machine as his drum machine. Very cool!
Here is an article that showcases some strange and unique instruments.

I LOVE the Yaybahar. Sooooo cool.
The Yaybahar is a new electric-free, totally acoustic instrument designed by Istanbul-based musician Gorkem Sen. The vibrations from the strings are transmitted via the coiled springs to the frame drums. These vibrations are turned into sound by the membranes which echo back and forth on the coiled springs. This results in an unique listening experience with an hypnotic surround sound.
This one looks like .... it might take a little practice.

Seen any other cool sounding or just plain weird musical instruments? Post them here just for the stupid fun of it.
