I was just sent this interesting link.
"Ignite captures the best of geek culture in a series of five-minute speed presentations.Imagine that you're on stage in front of an audience of hundreds of people, doing a five-minute presentation using a slide deck that auto-forwards every 15 seconds, whether you're ready or not. What would you do? What would you say?"
I wonder if this would make a good "frame" for students giving "stand and deliver" presentations to a class? Perhaps it would put a bit more excitement into the standard Powerpoint assignments.
