The waterfall was created by reproducing the space of C Future City in a three-dimensional space on a computer, letting water fall into it, and simulating the movement of water as influenced by the shape of the space. As people approach the waterfall, the flow of the water changes. It is a universe of water particles influenced by C Future City and the people there.

When a person moves, a force is applied in that direction, thereby generating a flow. The difference in the velocities of the flow and the surrounding area creates a vortex. Force is also applied by the cascading waterfall. The waterfall is changed by the presence of people, and vortices are born due to the movements of people.

Water is represented as a continuum of numerous water particles. The interaction between the particles is calculated, and lines are drawn in relation to the behavior of the water particles. The lines are “flattened” using what teamLab considers to be Ultrasubjective Space.

The work is affected by people, and is in a state of perpetual, continuous change.
