pulsing blue light. what does it meeeannnn?
Probably a status indicator like notification lights on cell phones. Since this will be am always on social integration box with messaging and so forth, I would be surprised if it does not have some sort of signaling to let you know about new messages. And since blinking LEDs would be too distracting in an entertainment center, pulsing is sufficiently discreet to work. Optionally hopefully.
