Pecha-kucha is an unusual method used to create PowerPoint presentations. The rules are simple. You can only create 20 slides, and you have to display each slide for exactly 20 seconds. This gives you 6 minutes and 40 seconds to give your presentation and get your message across (perfect timing for Toastmasters speeches!).
I am going to try it for my next presentation and I will let you know how it goes.
