The basic idea is to give designers and creative types 20 seconds for each of 20 slides, spreading great ideas and avoiding windbags. Since the concept started in Japan, this particular event was a fundraiser for relief efforts there.
My presentation can be found here. The video is a little hard to see at times, so I've included the slides below. Enjoy!
