I was very fortunate at the Global Apple Distinguished Educators Institute in San Diego to attend a keynote presentation by Drew Berry who is a Biomedical Animator. That means that he takes foremost biological research and creates animations to communicate that research visually. His animations are all done to scale and being able to listen to his working process and watch what he has made was mind blowing.
Take a look at his animation about the brain. The last part is amazing as Drew Berry explains what is happening on the screen.
