The resisting and resonating ovoids placed amongst the trees shine. The light of the ovoids and the light of the trees are autonomous: they shine brightly and then fade slowly, as though they are breathing.

When an ovoid is pushed, the color of the light it emits changes and the tone unique to that color echos. The light that originated from that ovoid resonates out to other ovoids and trees nearby. The tone resonates out continuously in the same way as the light, spreading throughout the ovoids and trees.

If a wave of light comes from the other side of the forest, it signifies that there is another person in that location. As a result, people gain a heightened sense of awareness of the presence of other people in the same space.
