This is a great example of trying to simplify a design that conveys incredibly complex content. The user selects a topic, a set of prepared questions are presented, the user selects the question he'd like answered and a video animates onto the screen with a talking head which then further explains the answer. Animated subnavs, tertiary navs, data files, imagery, video, and it all had to fit on one CD-Rom. The video editor, the Lingo programmer and I were *very* pleased when we saw the progress bar complete.
