Light is always in motion, just like sunlight in nature. Just make it a try then you will find its beauty. With the change of light source and reflective surface, together with the position and angle of hitting the light are constantly changing, the reflecting light effect will be quite different. Under the irradiation of point light source, the reflective surface of the curved sheets will show different reflection patterns, the final effect is like several dancing/leaping ribbons, then the whole space of the box is filled with changing light strips. That's why it's named Dancing Rainbow. The viewer will be able to explore the mystery for themselves!
