Here's a cheap and creative advertising example from Google Germany, promoting Google Video! By using see-through billboards, the message that Google Video gives you a realistic experience, as if you are seeing real people and scenes right in-front of you.
The see-through billboards, which were installed in Germany, have a typical Google Video Player layout. When you look at the billboard, you see the people, traffic and whatever is on the other side as if it were being played inside the Google player.
