Spheres of light float on the surface of the water of Japan&rsquo;s Shinmachi River. They move on their own, shining brightly, then disappearing&mdash;as if they are softly breathing.<br><br>When the spheres of light are touched by a person or receive an impact, the color of their light changes and they emit a musical tone corresponding to their new color. They can also resonate with the spheres around them, changing to the same color and emitting the same tone, creating a chain reaction.
