The trees of the Shiseido Forest Valley at Jewel Changi Airport shine 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 trees 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 trees, the tone also propagates through each tree, spreading continuously. The color-specific tone changes pitch according to the tree’s elevation along the Shiseido Forest Valley trail.

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.
