PechaKucha, from the Japanese term for the sound of “chit chat”, is a presentation format that is based on a simple idea: 20 images x 20 seconds. PechaKucha presentations are meant to be a fast and powerful medium for communication. At Boston’s 25th PechaKucha event on November 15, SSPP’s very own Jason Stevens explained in 400 seconds what posters mean to him, to at-risk youth, and why you should contribute to the Say Something Poster Project.
