MTV Stop-Motion through Balloons

So I know this isn't 3D, but I found it really cool and a really interesting form of animation. It's an ad for MTV where they have an animation on a series of balloons and then pop them as they follow with a camera... I'm not explaining it incredibly well, so you should just watch it. I really enjoy this clip though because it shows how you really can make animation out of anything and this form is interesting to me since it shows how you can really make animation out of anything and all the possibilities that are out there..
