Yes! Now I Know!
The HP commercials featuring The Kinks' "Picture Book" or The Robins' "Out of the Picture" to promote printing products are really cool. You've seen them ... people waving about plain, white frames that "capture" an image over the scene or "leave" an image in much the same magical manner. It's some of the most amazing moving image manipulation I've every seen. And thanks to the explanation HP has provided, now I know how they did it. Got broadband? Then watch the adverts here. MSNBC has a nice article about the whole shebang.
