Cool, this is the 2nd one of these I've seen. I guess a number of people just had this idea around the same time, hehe. I think increasing availability, quality and low cost of digital really enables cool stuff like this. Of course you could do it with film, but it's way easier with digital.
Edit: she did *really* well with the lighting and head positioning. Much better than the other I saw. Excellent stuff.
