This document summarizes a presentation given by Gudjon Mar Gudjonsson at Rubin in Reykjavik in 2010. The presentation discusses using Iceland as a "lab" to prototype and test new ideas and models for sustainable development across various areas like democracy, economy, currency and energy. It argues that Iceland's small size, educated population, and need to rebuild after its financial crash provide a unique opportunity. The presentation envisions convening large groups through an "open visioning platform" to collectively develop a new "world model" and invites others to help vision a sustainable future for Iceland and beyond.
