The ovoids of light standing on the surface of the Dragonfly Lake shine brightly together with the trees on the lakeshore. 

The light of the ovoids and the light of the trees are autonomous: they shine brightly and then fade slowly, as if breathing.

When an ovoid is pushed, the color of its light changes, and it emits a sound tone specific to that color. The light resonates out to the ovoids and trees nearby. The sound tone resonates out continuously in the same way as the light, spreading throughout the ovoids and trees.

When a light resonates from the other side, it signifies the presence of people or local animals. Perhaps people will become more aware of the existence of other living things in the same space.
