slides class is recommended (although article would probably be ok) - see e.g. Kopka & Daly "A Guide to LaTeX2e". What follows is based on this assumption.
\documentclass{slides}
\usepackage{graphicx} % if you want figures
\pagestyle{empty}
\setlength{\textheight}{210mm}
\setlength{\textwidth}{270mm}
\begin{document}
\begin{slide}
{\LARGE My Interesting Talk}
\vfill
{\large Albert Einstein}
\vfill
{Centre for Vision, Speech and Signal Processing\\ University of Surrey}
\vfill
\includegraphics[height=4em]{UOS.eps}
\end{slide}
\begin{slide}
Hello
\end{slide}
\begin{slide}
The End
\end{slide}
\end{document}

Currently you have to use the usual xdvi keystrokes (e.g. space and 'b') to click through your presentation. One day we hope to fix the mouse bindings for xdvi so that you can use the projector remote control. If anyone works out how to do this, please let me know.
You could alternatively create a "web" version of your presentation using latex2html. But it really needs someone to install a newer version of latex2html to make it worthwhile.
All comments and suggestions for improvements welcome.
