Brian Finley has put together an excellent Slide Show presentation to describe the benefits of PRT to people who are just being introduced to the subject.

It can be viewed online (only works in Microsoft Internet Explorer) or can be downloaded (it is quite large - 33.8 MB - so be prepared for a long download if you are connected to internet via a phone line) run locally on a computer or laptop. To unzip it you will need to get a copy of WinZip if you don't already have one. All the computer needs is to have Microsoft Internet Explorer web browser. For best results when showing the presentation to a group, a overhead projector connected to your computer would be best.
