How well do animations work? I came across one yesterday on Alfred Wegener, and today there is a very nice one in the NEJM on yaws (remember the old medical school joke: ‘what’s yaws? Thank you, mine is a pint of bitter’. I enjoy them, and feel they stick in my mind more than just looking at some text, but would like to know more. And yes, I have looked at the multimedia textbooks, but I am still uncertain. Or perhaps this is an ill-framed question: there are animations, and animations, just as there are lectures and lectures.  [direct link to this post]
