Can anyone please send me a link to this NATIONAL GEOGRAPHIC youtube video

Im looking for the intro video that used to be played on national geographic programs, and is used on most nat geo dvd doentaries. Its hard to describe but it has like the nat geo symbol and it looks like a bookcase and has some orchestral music playing in the background. If someone can find this anywhere on the net in the form of a video for me, i will award the first person 10 points, thanks :)
