The light of each tree is autonomous; slowly breathing, it shines brightly and then fades.

When visitors or animals approach the trees, the light changes color and a tone resonates outward. The neighboring trees will also resonate, switching to the same color and tone. This response will ripple outward to the surrounding trees; it will finally reach the trees in the mountains, and the mountains themselves will resonate.

If a wave of light rushes from one direction, it signifies the presence of a person in that location. If a wave comes from the mountains, it means that animals are there. As a result, the audience will have a heightened awareness of the presence of other people in the same space and of animals in the forest.
