Jellyfish is an interactive sound installation. It’s an extended version of my previous work “Sound Marbles”, which can create the composition of sounds by simple interaction. Jellyfish uses the simplest way of interacting with objects to create sounds; it’s touching and covering holes by hands and that way of creating sounds was inspired by musical instruments. In order to make people enjoy musical performance and generating sounds, I apply the jellyfish shape for the output of this work, and sounds also remind one of deep-sea sound waves. Combination of musical instrument and sea organism can give inspiration and imagination to people that makes it enjoyable and fascinated.

There are 48 holes on the surface of hemisphere, and each of holes represents a musical note. 48 musical notes are composed of 4 octaves, and all of sounds are recorded ones by MIDI. By covering the holes with hands, people can create the sound composition easily. 48 photo resistor sensors and LEDs are under the surface of it and it detects the distance between hands and sensors. All of sensors are connected to Arduino board, and processing program manages their data signals.
