Animation of biological function doesn’t really contribute much to the research side of things (despite the claims of some press releases); but the movies can be good teaching tools.  Now there’s a site (http://www.molecularmovies.com/) that has aggregated a number of the animations that are out there.  Many of the movies can be freely used for teaching. I haven’t seen any mention of this in the blogworld, which surprises me: it seems like a useful resource.
