Have you heard about Pecha Kucha? This technique for making presentations is perfectly suited for Podcasting.
What is Pecha Kucha? A presentation technique whereby each presenter is allowed 20 images, each shown for 20 seconds each (or 6 minutes 40 seconds). This keeps presentations concise and the interest level up.
Pecha Kucha (which is Japanese for the sound of conversation) has tapped into a demand for a forum in which creative work can be easily and informally shown, without having to rent a gallery or chat up a magazine editor. This is a demand that seems to be global – as Pecha Kucha Night, without any pushing, has spread virally to over 100 cities across the world. Find a location and join the conversation.
