Read Pecha Kucha: Get to the PowerPoint in 20 Slides Then Sit the Hell DownThanks to Dori for this tip.Dori notes that, “The 20/20 is strictly enforced but you have a more structured set of themes to generate discussion than an open mike, where enforcing time limits is more of a challenge because there is no structure. It would be both auditory and visual, which would provide some interesting fodder for what kinds of visuals each group would use.” -Dori
