Transience, the theme chosen for the sixth Design Display exhibition, represents more than a philosophical inspection. Two designers who deal with the concept of impermanence take stage: Maarten Baas destroys in order to create, and Dave Hakkens develops concepts of sustainability. For the Smoke series, Baas took iconic design pieces and torched them until they were left charred. And with his concept of Phonebloks, Hakkens plays on the resemblance between manufacturing electronics and making Lego blocks.
