I have always loved having my slides, for various talks, presentations, and lectures in an open and easy to use format and frankly hated using powerpoint. Powerpoint tends to bog down, have a horrible interface and generally suck out my soul. The downside is beamer, the standard slideshow package of LaTeX tends to be bulky requiring many many more lines of code than content, something LaTeX tries to avoid. The answer is PanDoc. PanDoc is a system for generating documents in one format and outputting them in another. It can also do slidewhows outputed as a beamer tex file or as one of several HTML slide show formats.
