On Tuesday afternoons I turn into Adjunct Professor Alter, teaching sustainable design at Ryerson University School of Interior Design in Toronto. After class I was hanging around TreeHugger's virtual water cooler describing the long (297 slide) presentation when TreeHugger Mike suggested that I should video them. That's hard to do, but I thought there must be other ways to present the information.
Then I remembered the Pecha Kucha, invented in 2003 by Astrid Klein and Mark Dytham as a way of forcing long-winded and slide-heavy designers to make their presentations concise and fast-paced, limiting them to 20 slides at 20 seconds each, about the time it takes to read this much copy. So here is Pecha Kucha TreeHugger slideshow about why that Volkswagen ad was right, we should think small.
