{Using animations within \LaTeX{} documents}
{Michael Doob}
{\TeX{} has always been in its heart a program for creating beautiful
books. As \TeX{} matured, markup was simplified using \LaTeX, packages
for creating beautiful tables of contents and indexes appeared, and
colour was added. Graphics packages were also added allowed beautiful
illustrations, but the resulting output was in essence a book. This era
of progress is disappearing.

We now read novels on our smart phones and mathematical papers on our
tablets. The objects being viewed are less like traditional books and
have potential to be much more exciting. Fortunately, \TeX{} is flexible
enough to adapt to the changing environment.  As a step supporting this
change, we survey the varied techniques available to create animations
within \LaTeX{} documents.}
