A corda Árvore

Check out this Sundanese Low-Tech waterfall drum machine !!

As discribed by Palmer Keen who stumbled across it and shot the video on his phone:

'The Sundanese of West Java are expert soundmakers. Other than peppering their rice paddies with huge buzzing windmills to entertain the rice goddess, folks in these parts also enjoy experimenting with other soundmakers - here’s a water-driven drum machine with spinning sticks smacking out a rhythm on biscuit tins and a tube of bamboo. Found in the countryside in Ciater, West Java.'

Check out this "Physical Sequencer" as described by it's maker Michalis Shammas ! 
In his own words:
'It consists out of strings with suspended weights that are free to slide on pulleys to enable a continuous frequency spectrum.
You can use a simple "actuator" system to automate the instrument like a sequencer.
Everything is amplified with piezoelements. It is a work in progress.'
