Picture of Bananaphone: A Touch Capacitance Synth
I was recently inspired by a Kickstart project which used Bananas as sensors to control a video game on a PC.  I've done some video game controls using the Propeller in the past, but I thought this would make an interesting synthesizer project.

It would be ironic to play "Yes, We Have No Bananas!" with Bananaphone. You made The Humongous laugh. He salutes you.
Did you try to play some Velvet Underground tunes with it ? I think that John Cage will be pleased.

that is amazing! how useful are bananas?! the skins are also great for removing insolubles like metals from water - great for the wastes management industry.
