Saturday evening I participated in a PechaKucha-style evening of presentations sponsored by the Bowen Island Arts Council as part of the Canada-wide Culture Days events.
For those not familiar with PechaKucha, it requires you to make your presentation precisely 20 slides long, with each slide lasting precisely 20 seconds — so the entire presentation is exactly 6:40 in length. You can of course choose your own slides, but you are encouraged to use few or no words on your slides, so that the audience listens to what you are saying instead of reading your slides.
Since the idea of doing this as our contribution to Culture Days was initially my idea, I felt both obligated and inspired to be one of the presenters. I challenged myself to see if I could capture the essential ideas of complexity and why civilizations always collapse, into this short a presentation.
