I give the presentation linked here in Web design classes and workshops. Instead of using Powerpoint to create the presentation, I used Flash. The file is 27 KB. All the text and images were created within Flash MX (there are no bitmaps).

> Flash Examples Index

The buttons for a pseudo Powerpoint in Flash (like this one) use the ActionScript methods nextFrame() and prevFrame(), which are pretty simple to figure out. Put the buttons in their own layer. Each animation is a Movie Clip in a single frame within the main movie.
