Hate Long Rambling Speeches? Try Pecha-KuchaAt a pecha-kucha, an event conceived by Tokyo architects Mark Dytham and Astrid Klein, presenters have 6 minutes and 40 seconds — or 20 slides, 20 seconds per slide — each to show off a talent, unveil an invention or just share an idea. The idea is to put limits on speeches and force the viewer to focus and think.
