Publish annual anthology (print and/or virtual) of winning concepts and the process behind them. Includes introductory chapter exampling the different steps. Would be visual and edited with annotation. The point of this is to share the ideas and realization that come out of the challenges to a wider audience for learning purposes.
An annual anthology of various concepts (perhaps winning and other popular ones) with annotated commentary about how the process evolved and how the winning concepts were realized.
PURPOSE: The purpose of this would be for sharing the creative learning of those who give their time to share ideas to challenges. This would allow others who are not part of the Open IDEO community (but also us) to reflect on some really innovative solutions to tough problems. This would allow someone who is specialized in one of the challenge themes to get a fresh take, or perhaps reconsider an old solution that was not timely in the past, but is relevant today.
REACH through TRANSLATION: Because it is more refined in scope and breadth, it could be translated into different languages, starting with those where some of the issues target (e.g., Spanish for the Gramean challenge).
It could promote participation because it would be a de facto advertisement. It could also be used in universities (in classes), among organizations, and public libraries everywhere.
