I really like the idea! One issue though is that the content seems to "stream" much slower than what's being spoken. The result is that I'm sitting there waiting to see whats going to come, even though its already been said which makes it hard to focus on whatever new information is coming.
The animations / drawings themselves are solid too. I think there's more to play with wrt the dimensions and space of the background. It would be nice to see it zoom in and out for example.
