So Ive been wanting to do this mod for a few years and have finally got around to doing it. It requires hardwiring up a LCD behind the apple logo and having your macbook recognize it as a secondary display. Much better than just inserting colored gels to change the color, because now you can change it at any time to any color, movie and even the itunes visualizer. You can even have your isight camera. Heck anything I want! It is amazing and works perfectly! I thought you all may appreciate this!
and here is a youtube video of it
