The trees of Topiary Walk 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.

If light resonates out  from deep within, it means that there is someone over there. Perhaps people will become more aware than usual of the presence of other people in the same space.
