I’ve been wanting to get more into creating sound sculptures and things that can play themselves, so I knocked together this quick prototype for an idea I had using wind to pluck strings.
I used 4 dessert pots to act as a windmill that turns a metal rod with the plucking device attached. I had to experiment with what to use for the plucking bit and in the end the corner of a train ticket was the best! The strings are banjo strings and are set up to surround the shaft with the train ticket.

Nice one! I did something similar:
2008 and 2010
(Not saying yours isn't original – i'm saying great minds think alike!)
goddamnit! they look startlingly similar to the MKII windjo I've just finished… only yours is far more polished and doesn't sound like a donkey playing a steel drum.
I think i need to do more researching to make sure I'm not making stuff that's already been done!
