Pecha-Kucha

Mark Dytham and Astrid Klein, two Tokyo-based architects who have turned PowerPoint, that fixture of cubicle life, into both art form and competitive sport. Their innovation, dubbed pecha-kucha (Japanese for "chatter"), applies a simple set of rules to presentations: exactly 20 slides displayed for 20 seconds each. That's it. Say what you need to say in six minutes and 40 seconds of exquisitely matched words and images and then sit the hell down.

It sounded like a good idea. Speakers have to plan very carefully and rehearse repeatedly to make sure their speech is going to synchronize correctly with the slides, which makes for a more polished speech. They have to edit mercilessly to boil their subject matter down to 400 seconds, which makes it more interesting and dynamic. And if they suck, well, you don't have to wait very long for them to go away!
