Another TED video of Hans Rosling presenting data with Gapminder. This time on The Truth About HIV, in which we learn a lot about the diversity of Africa. This is where the trendalyzer shines.
And albeit the severe topic I also wanted to bring your attention to a detail of his presentation technique. Hans Rosling uses an old-style pointer instead of the laser ones we see so very often these days and his presentation makes it very clear why that is a better choice.
You might want to subscribe to the TED videos as a podcast on iTunes. On the web however you will be able to get to the translations, e.g. the video mentioned here is already available with french and swedish subtitles.
