PKN or PechaKucha Night is a presentation style that originated in Japan in 2003. It involves presenting 20 slides for 20 seconds each, with the total presentation time of 6 minutes and 40 seconds. There are several synonyms for the PechaKucha Night, such as Ignite Talks, lightning talks, micro-presentations, and rapid-fire talks. The speakers in PKN Nights usually present on a wide range of topics, from art and design to science and technology. PKN Nights have become increasingly popular over the years, and now many major cities around the world host their own PechaKucha Night events. These events provide a platform for people to share their ideas, experiences, and knowledge in a concise and engaging format.
