This file is now probably dispensable since almost everything I produce is available in either plain text, html, or pdf, and nobody should have problems reading any of these, given the capabilities of widely availabel internet browsers (e.g. Firefox) and PDF viewers, including Acrobat reader, xpdf, kpdf, okular, evince, and others.

These are formats which are publicly specified and for which there are freely available readers which work on many types of computers and operating systems. (I use only Unix and Linux operating systems running on Suns and PCs). Some governments have introduced legislation requiring publicly funded organisations to use only public, open formats for documents. (I believe Peru led the way, years ago.) All governments should do the same.
This can be used on linux, a variety of unix platforms, windows, and macs.
However, most of them are produced in Latex. This has faclities for producing both postscript and PDF files. In the past I produced postscript which I converted to PDF using ps2pdf or distill. Nowadays I simply use pdflatex to produce papers and presentations in PDF format, and do not produce a postscript version. Occasionally I also use OpenOffice, e.g. to convert html to PDF, or in some cases to produce PDF from a word file created by a collaborator. (Now superseded by LibreOffice available from http://www.libreoffice.org/)
Most of the papers and older presentations are in A4 Portrait format (long edge vertical). Since about May 2001, have prepared slide presentations in the landscape format, which is more suited to fill a typical computer screen which is wider than it is tall. These need to be viewed in "Landscape" or "Seascape" mode (rotated 90 degrees to the left). Your browser should either automatically detect the orientation and show it correctly, or provide a mechanism for rotating 90 degrees left or right. If you are using "gv" it may show the slides in landscape format but upside down. In that case select "seascape". On some displays you may have problems with slides that use colour, if you have anti-aliasing turned on in "gv". You can solve this by turning it off, though the text will then look slightly poorer.
If anyone would like a copy of my latex style file used to produce the slide presentations, just ask. (Email: A.Sloman AT cs.bham.ac.uk).
28 Jan 2006: I found a web page commenting on the quirky style of a presentation I gave in 2002, so I wrote a little response here, explaining why I do what I do and why I don't like flashy gimmicky presentations.
