While in Tokyo last week, I had the good fortune to attend a PechaKucha event in the place where it all started. PechaKucha is a simple idea delivery engine. The concept was invented by architects Mark Dytham and Astrid Klein as a clever way to keep architects from hogging the microphone and going on too long about their projects. Each presentation is limited to 20 slides which automatically advance after 20 seconds (20×20). The rest is history.
