A very interesting way to engage individuals on a personal level via video. It startled me the first time around (see :56). I wonder how quickly the novelty of providing subtle dynamic elements to video would wear off, but if done properly, might have a place in a nonformal educational setting for children ... a new type of personalized learning experience.
Ah, and I may have altered the web link a bit to make it a bit more appropriate for our class :)
