PechaKucha 20x20 is a simple presentation format where you show 20 images, each for 20 seconds. The images advance automatically and you talk along to the images. The presentation format was devised by Astrid Klein and Mark Dytham of Klein Dytham architecture. The first PechaKucha Night was held in Tokyo in their gallery/lounge/bar/club/creative kitchen, SuperDeluxe, in February, 2003. Klein Dytham architecture still organize and support the global PechaKucha Night network and organize PechaKucha Night Tokyo.
