When things blink and flash they are cool, when they are in a particular sequence with multiple colors and sound, they are rad. You could say the same for the KDDI Light Pool clamshell phone. On the outside, you’ll see a total of twenty-two LEDs in the shape of triangular windows arranged in a criss-crossing grid-like pattern. These LEDs are meant to display a touch of personality, lighting up in 100 different patterns sequenced with music. Patterns can indicate an incoming call, email, or whatever you prefer.
