We start each (logical) slide with
\foilhead{Title of first slide}
followed (optionally) by a \pause in order to pause the output immediately after the title. The next few lines are the content of the first slide — in this case a list:
\begin{itemize} \item look at the source!\pause \item to compile this file\pause: \begin{enumerate} \item \texttt{\color{red}pdflatex Example} \pause to create \texttt{\color{red}Example.pdf}\pause \item \texttt{\color{red}ppower4p -n Example.pdf Example2.pdf} \pause to generate \pause \texttt{\color{red}Example2.pdf}\pause, which contains the presentation \end{enumerate} \end{itemize}
There is nothing to comment on here except to notice the \pause and the \color{red} commands, which do the obvious thing. I normally don't use so many \pause's, but I'm trying to make the point that you can use as many as you want.
The second slide contains some mathematics and a hyperlink:
\foilhead{Another slide}\pause This slide contains Euler's formula\pause: \begin{equation*} e^{i\pi}\pause + 1 \pause = 0\pause \end{equation*} which was recently \href{http://news.bbc.co.uk/1/hi/magazine/3721406.stm}{voted} the most famous equation of all time \pause jointly with Maxwell's equations!
The only thing worth noting is the \href command which inserts a hyperlink. The word 'voted' will appear in a different colour, because of the colorlinks=true directive to hyperref in the preamble.
The last slide contains an example of a fancy page transition. I think they're quite distracting, whence I don't like using them except perhaps as a final flourish at the end of a presentation.
First of all we start a new slide (without a title):
\foilhead{}
One could also force a new page with the LaTeX command \newpage, but this is logically different than starting a new slide.
The next command contains the fancy page transition:
\VISplit
There are many other equally fascinating page transitions defined in the aptly named pagetrans.sty.
Finally we have some content:
\begin{itemize} \item and that was an example of a page transition\pause. And that's all.\pause \end{itemize} \vspace{1.5in} \begin{center} \large Enjoy! \end{center}
As usual it only remains to close the document:
\end{document}
and that's it!
It remains to compile and post-process.
