The spheres of light floating on the surface of the sea are each autonomous, shining brightly, and then disappearing—as if they are softly breathing.
When the spheres of light are touched by a person or receive an impact, the color of their light changes. The light color resonates to the spheres around them causing those spheres to change color, and in turn those spheres resonate the color to the spheres around them, the color resonating out continuously from one sphere to another.
