Wade among interactive koi in this stunning art installation

TeamLab creates gorgeous interactive art installations, like this beautiful piece poetically titled Drawing on the Water Surface Created by the Dance of Koi and People. It's not a video loop, but a program where the swimming koi interact with each other as well as the people wading among them.

From their site:

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.
