This clever animation from Atama Studio was produced to illustrate the potential of NFC on the iPhone 5. You'll notice that, as each CG iPhone falls, it triggers the image on the phone next to it. The effect is most dramatic at the end, when a huge grid of fallen iPhones create a single "display" and produce one huge image.
Of course, the iPhone 5 came and went without a NFC bone in its body. Still, this is a pretty cool animation. The elevator bit is my favorite.
