The video we had to watch about presentations called Hans Rosling: Debunking third-world myths with the best stats you've ever seen.was a really cool presentation. I loved how he had so much movement and movement within his presentation. It was almost halfway through (I didn't see a timer to mark a certain time point) when he was giving the information on the graph that had a high peak in the middle and colors for each piece of information start falling from the top right into place! I am definitely going to try to learn how to use some of his techniques in my presentation, I don't know what you mean Lisa, by the question what are his key elements? If you let me know in a comment I will come back in to add more to my post.
