I appreciate the effort, but I found these animated illustrations confusing. Which part is what? On which sides are they bound? How are they attached? How do they interact? When are the shapes "scrolling" and when are they animating themselves? I like seeing the concepts in action, but I came away with little idea of what the concepts were other than that they were different - well, little more than I started with. More size, context, and interactions would make this vastly more educational, I think.
