Best PowerPoint You've Ever Seen...and it's on Global Poverty Statistics

Technology, Entertainment and Design (T.E.D.) is an annual gathering in California of the so-called "brightest and best" and they recently started to post video of past presentations. I stumbled across this presentation by Hans Rosling on global poverty statistics in 2006. (He did a follow-up at TED in 1997.) I've seen a lot of presentations on global poverty statistics and read the UNDP Human Development Report over the years, but Rosling blew my preconceptions out of the water. He had people applauding in the middle of his talk! Smart, funny and gives the best darned PowerPoint presentation I have ever seen. To top that off, the tools he used for his presentation are available free at Gapminder, the non-profit organization Rosling founded to combine information technology and statistics to better understand poverty and development.
