Beamer All the Way

Why beamer Use of LaTeX results in pdf files which could be viewed practically on every computer. We need to use LaTeX anyway to output formulas, so it is very natural to use LaTeX to create the whole presentation. Since talks are very different from articles and books, one needs to use specialized documentclasses. beamer is currently far the most popular and powerful.
My first beamer In contrast to the common belief beamer is rather simple. One can learn to make a very decent presentation (nice, clean, easily visible, with basic dynamic pages) in 5 minutes. The main goal of my talk is to teach everyone this basic technique.
Dynamic pages More advanced technique to build dynamic pages.
Customization Using built-in options one can change how things look like.
Picture, sound, movie! How to include or generate graphics? How to include sound or movie (using movie15)?
Misc Making presentation. Getting help.
