The resisting and resonating ovoids are autonomous. When an ovoid is pushed over by people or blown by the wind, it rises back up as the color of its light changes and a tone specific to that color resonates out. The surrounding ovoids respond one by one, 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.
