The densely packed, standing ovoids of light are autonomous. When an ovoid is pushed over by people moving through or blown down by the wind, it rises back up as the color of its light changes and emits a tone specific to that color. The surrounding ovoids respond one after another, continuously changing to the same color and emitting the same tone.

When the wind is not blowing and the people nearby are not interacting with the ovoids, their lights begin to blink slowly.
