A good idea to make it light up: (and waste money and power)
Put inside it a blue LED. Cut the circle out, put plastic in it, and connect the LED to the plastic so that it lights up. Also something to remember:
If you run out of room, it fills Master Chief's hand.
Master Chief is a Spartan. Spartans are HUGE. That chip is HUGE.
I'm guessing that it is about 4 inches long so make it bigger if you don't have room. Or just don't do it. It's a suggestion.
