undercurrent

Lines of light sway in the wind, drawing invisible currents through the forest.

Side-emitting optical fibers are stretched between the trees. The wind moves the lines, night dew turns into small drops of light, and people walking by change how the lines look. These small movements come together into a single wave — like the flow of a river, the sound of the trees, the echo of music playing far away.

Under this ground, hot spring water is still flowing today. Water under the earth, wind between the trees, music that never stops through the night. Among these currents, a single vein of light.
