Created by TeamLab in Japan, where people can walk into the water and the movement of the koi is influenced by the presence of people in the water and also other koi. When the fish collide with people they turn into flowers and scatter. The trajectory of the koi is determined by the presence of people and these trajectories trace lines on the surface of the water.

The work is rendered in real time by a computer program, it is neither a pre-recorded animation nor on loop. The interaction between the viewer and the installation causes continuous change in the artwork. Previous visual states can never be replicated, and will never reoccur.
