It's a really cool ad, almost like Google Earth in how you can focus in one one area and enlarge. I just wasn't expecting to randomly see a Halo 3 ad in it...heh.
It's not video game related, but they have a video of a fighter jet in there too, and when you click on it, it actually plays.
Found an Xbox360 Live logo and a Transformers ad too. It *does* seem a bit perculiar to put a Halo 3 ad on a car (I mean the pics with the screenprinted Halo ad at an autoshow) - do you think that somebody drives that car around?
