MagicPoint X11 Presentation Tool

Rex Walters wrote in to tell us about MagicPoint, a presentation package (ala PowerPoint) that will compile and run under Linux. Open Source, LaTexesque input, easy keyboard controls, ability to 'swallow' Xclients into it. I doubt most of you have a need for such an application, but by the same token, I bet a good number of you consider this type of application a last unbreakable connection to some 'other' OS, so this may be worth a look.
