On Pecha Kucha

Back to presentation skills,   today, while working with one of my colleagues, Avi Yaeli, on a presentation, I've learned a new concept - Pecha Kucha.  This is a presentation pattern, in which the presenter presents a topic in 20 slides, and spends on each slide 20 seconds,  total of 6 minutes and 40 seconds per presentation. 
There is a youtube presentation containing Pecha Kucha style presentation about how to prepare Pecha Kucha style presentations.   I should try it once.  There are also Pech Kucha nights which seems to be marathon of Pecha Kucha presentations.
