This piece was created as part of my graduate thesis which explored interactive responsive sculptures that behaved differently based on the user's proximity. Spines extend and retract in unique sequences based on how close the user is to the piece. The spine's movement is combined with lighting and audio responses.

The sculpture incorporated an ultrasonic rangefinder and a capacitive sensor to read distance. An Arduino micro-controller processed the signals and controlled the servo position and LED lighting sequences. A contact microphone connected to a metal comb inside of the mechanism generated the sound responses.
