This document outlines an assignment to envision desired futures and sketch provocative proposals to define levers for change. For success, the future vision should appeal to various actors, include creative proposals and levers working at different levels involving many actors. The language should be clear and inspiring using metaphors and images, balancing realism and provocation. Conditions for success prioritize creativity and open-mindedness over coherence, with no self-censorship and flexibility in lab design alongside awareness of language usage and a good experience.
