The Spoonbox

I built the Spoonbox out of wood, plexiglass, zinc plates, measuring spoons, and closeout computer audio parts. It hooks up to a CD player which plays through a small amplifier that I designed which cause the spoons to dance. There are small speakers behind the spoons that vibrate in response to the sounds on the CD which I composed using low frequency sine waves and kitchen sounds. The speakers, in turn, blow small puffs of air into the spoons which cause them to jump in rhythmic patterns.   I've recieved a lot of requests for these Spoonboxes, so I've decided to make multiples, like a little cottage industry here at home.  Here's a video of the prototype:
