Color Changing Mood Light is designed by Shiu Yuk Yuen and is based on the concept of color therapy.  The item is turned on by slowly pressing down the top surface. Then the light will start changing, covering the full color spectrum.

The colorful lit cubes are made of silicone rubber, a soft material, not at all rough or inaccesible to touch. A really fun and relaxing gizmo to have around.
