'Dangerous ideas' is the theme of the third instalment of The Cooler Lumpur Festival, which challenges urbanites to bring contentious ideas to the fore. Ideas – creative, newfangled, counter-intuitive, fearsome – hold the power to instigate change and reshape the world. And that is what the organisers are aiming for: to create discourse and prod audience to look at things in a different light. Returning festival-goers will be treated to a well-edited selection of lectures, panel discussions, screenings, workshops, as well as the highly anticipated Poskod Journalism Campus. Here are some of the best things to do at the three-day festival.
