In 2001 I worked on shots for a PBS special. The series animated different evidence of evolution and the changes and factors that go along with it. Evidentially, our eyes have evolved, and I spent some time learning about that, and them creating two animations of the human eye, and its evolution related features.
Most of the work for this Series was done on SGI's. The models for these shots was done on SGI, and the textures helped along in IRIX based Alias Studio Paint, but NT computers had just made their great dawn, and the compositing for these shots was done in Premiere and After Effects. All animation for the series was rendered in HD.
Animation Technologies produces medical and technical animation for legal defense cases. Anything from a plane wreck to a toaster oven malfunction. It has to be very legally accurate, and defendable in every way in a court room. I was there to work on animation for a case involving a drug produced by Johnson & Johnson, and its effects on a weak heart.
I do not have the animation to show but it involved this model of a heart to become visible in cross section, demonstrate the valves working, blood flowing, beating at a normal rate, and then explain the irregularities that can occur, pointing out the electric signals that stimulate the timing of heartbeats, and how they are disrupted.
