Top 5 Shadow Animations on the Web

Recently, I’ve been seeing a lot of these type of videos around (what I call “shadow animations”):


I also saw a couple commercials and games on TV with this particular style. So, I’m thinking, where did this “shadow” style of animation come from? Have you seen this style being used more and more, or not really? My first real “exposure” to this sort of shadow imagery was way back when Apple was advertising their iPods (remember the silhouetted figures with the white cords to the iPod?).

If you find any other examples of shadow animation, please post them below for others!
