The whole thing that powers a PechaKucha event -- whether it's a city-based PechaKucha Night or a "Powered by PechaKucha" event -- is the "20 images x 20 seconds" format. WATCH is where you'll find presentations from all over the world -- get inspired!
I have used this presentation format in my class and it really causes the students to think and plan accordingly.
PechaKucha show digital literacy and act as inspiration.
