The objects of light standing on the surface of Mitarashi Pond are autonomous: they shine brightly and then fade as if slowly breathing.

When an object is pushed by people or is blown by the wind and tilts, the color of its light changes, and it emits a sound town specific to that color. The light resonates out radially to the objects nearby. The sound tone resonates out continuously in the same way as the light, spreading throughout the objects.
