The forest in the ravine shines brightly. Each tree’s light is autonomous, shining brightly and then fading, as if it’s breathing.

As people pass nearby, the light of the tree changes color, and a tone specific to that color resonates out. The light of an individual tree spreads radially to the neighboring trees. In the same way that the light is transmitted between the trees, the tone also propagates through each tree, spreading continuously.

If a wave of light comes from the other side, it signifies the presence of people there. People gain a heightened sense of awareness of the existence of other people in the same space.
