If you happen to have some spare time on the web (whenever…) and still looking for strange, useless, stupid, incredible, useful creations, then you have to give a try to the Arduino Forum.

I chose to dedicate some posts per week just talking about odd Arduino Forum machineries.

This one seems crazy: [Jochem] made his first year thesis about a vegetal-to-digital way of producing music.

This is the brief descrption from the Forum thread.

This is a project I made for the first year fine arts at HKU in Utrecht. It uses 12 nails in a wooden fruitbowl to sense the resistance between different fruits and vegetables. This then goes to an arduino mega and gets send to max/msp with the arduino2max patch.
I then used some low frequency oscilators and a heavy subwoofer for that real body feel.
