I just saw a fascinating presentation about creating more powerful presentations by NOT using PowerPoint. Indeed, the talk illustrates the point by using live dancers on the stage with the presenter to help illustrate the points of the message. The speaker, John Bohannon, is a microbiologist, and has started a contest called “Dance Your PhD,” encouraging science researchers to employ professional dancers when speaking or illustrating their concepts to a live audience. Search for this term on www.youtube.com and see some of the winning entries.
I think you will enjoy and appreciate this TED talk.
