Jellyfish

This is an interactive installation in which small parachutes move up and down in the air, as if jellyfish are swimming in the water. The parachutes move away from someone who approaches them. It lets viewers feel invisible air, space, and time. Eight parachutes are installed in front of a window, being hanged by a fishing string. A step motor winds them on a reel to control the parachutes moving up and down. In each parachute, a sensor is installed to detect the approaching figure around it. The movement of parachutes is intended to imitate the movement of jellyfish, using the air. When a parachute moves up and down, the air comes into it, and it billows out and deflates in the air.
