Pecha Kucha Częstochowa-Pecha Kucha presentation is a presentation style in which 20 slides are shown for 20 seconds each (6 minutes and 40 seconds in total). The format, which keeps presentations concise and fast-paced, powers multiple-speaker events called Pecha Kucha Nights (PKNs).
Pecha Kucha Night was devised in February 2003 by Astrid Klein and Mark Dytham of Tokyo’s Klein-Dytham Architecture (KDa), as a way to attract people to SuperDeluxe, their experimental event space in Roppongi, and to allow young designers to meet, show their work, and exchange ideas.
