Note: To compile the presentation as it is, you
need to download the Beamer class (see the references page of the .pdf presentation
for the website), then create a folder and download into this folder all of
the following: the LaTex file, the pictures, and the movies. Otherwise, you
need to remove the references to the pictures and movies, since the beamer file
will not compile if these are not in the same folder as the .tex file.
