Our goal for the Finger Symphony was to create an interactive, visually engaging sound machine, approaching a musical instrument. We were inspired by the Intel Animusic Machine (https://www.youtube.com/watch?v=PCIkbr9HCcw) that uses mechanical movement to create an engaging visual and aural experience. We initially wanted to use marble-launching solenoids to hit targets and produce the sound, but refined that to solenoids directly hitting the sound making target for time constraints.
