2. Wooden Board + Coins + Plastic Card

Materials Used: A piece of wood I retrieved from my parents-in-law's basement,  2 quarters, 2 rubber bands, plastic card, Korg CM-100, Macbook Pro, MOTU 4Pre, SuperCollider

How it was made:
A contact microphone attached to the board is feeding the sound into a Macbook. Then SuperCollider, a text-based audio processing program, is changing the sounds according to my customized digital signal processors. Whenever you see my right hand moving towards the screen, I am turing on/off a particular digital signal processor.
