The PechaKucha concept is simple: 6 minutes 40 seconds per speaker, which means 20 images with 20 seconds each. The 2016 edition in Les Halles de Schaerbeek hosted 9 speakers. They talked about privacy, happiness, entrepreneurial kids and much more. The videos are all available online as of now, so have a look!
