Very nice demo,
I have to disagree with some of the previous posts that physicians do not care about interface. I'm a Medical Software vendor, and I'd say that they care about the interface very much. There is a perceived "difficulty of use" when the interface is poorly designed. As long as key functionalty is there, interface is one of the most important factors whether users admit it or not. I'm not sure how much animation is overkill, but visual cues are important to usability.
