Edgar Aroutiounian has a nice post about adding animations to PDF files with Emacs, Org, and LaTeX. If you’re an OS X user, he also explains how to load a minimal TeX distribution rather than the huge MacTeX distribution.
The real magic is putting an animated graph into a PDF file. It’s surprisingly easy to do and doesn’t require much more than Emacs, Org, and LaTeX. Definitely worth reading if you think you might want to do this someday.
