Ignite & Pechakucha

"Ignite is the name for a particular type of event that is held throughout the world—organized by volunteers—at which participants speak about their ideas and personal or professional passions according to a specific format. The event holds the motto, “Enlighten us, but make it quick!” (…)  In Ignite each speakers gets 5 minutes, and must use 20 slides with each slide advancing automatically after 15 seconds, forcing speakers to get to the point, fast."

"PechaKucha or Pecha Kucha (Japanese: ペチャクチャ, IPA: [petɕa ku͍̥tɕa],[1] chit-chat) is a presentation style in which 20 slides are shown for 20 seconds each (six minutes and 40 seconds in total). The format, which keeps presentations concise and fast-paced, powers multiple-speaker events called PechaKucha Nights (PKNs)."
