Pechu kucha hit our family reunion, and it was, predictably, unpredictable, exhilarating and informative. The format: 20 slides, 20 seconds per slide. You have to talk fast or say very little! Then there's a dramatic change of topic and away we go again. Examples:
The family reunion was brilliant. Relaxed, happy, friendly. Instant rapport among 60-odd people. Tennis swimming cricket walking biking talking cards. It's great watching those cousins size each other up, latch on and make superglue bonds. The secret is simple: having the reunions so often that they're just part of life. We do it every 5–7 years.
