oh, we are here to learn.

Isnt the bowl the oldest looping instrument?
As your hand makes a looping movement it creates a drawn...
Well you can achieve this with a cat, too :-)

sure, we can make a lot of mechanically looping instruments still.
A painter friend suggested to make an endless rainmaker:
A circular tube on a bycicle wheel, maybe wind driven.
In the tube there are stones or rice and the walls are fitted with 
varying tongues  so it keeps changing sound while it turns... you can 
nearly compose like for a music box, but its still much more 
irregular and softer sounding...
