While we are on the subject of movies and presentations, you may not know about a nifty little app on your mac called Quartz Composer.
Basically you get a slick visual programming language for creating real time graphics manipulations (think about real time openGL, but laying out data flow visually instead of code); it also happens to be very well integrated into quicktime and the apple development environment. The nice thing is that you can play back quicktime movies (pan and zoom smoothly in real time) and overlay crisp text, that looks great on full screen projection. It's a little more work than doing stuff keynote/powerpoint, but pretty quick (and quite fun) once you get used to it. I think a lot of information can be conveyed more efficiently with animation (and you can use nice high resolution images and crossfade in real time etc.). I've posted some examples here (you will need a mac, OS X 10.4): http://www.scripps.edu/~yadavm/qtz/ (I can't post some of the really good quicktime examples since the movies are 100MB, but I put one in there as a zip archive). I took great pleasure in starting my defense from iTunes.
