I just stumbled upon this project, and find it incredibly inspiring. Design for Africa is a project by two recent Design graduates, one from Germany, the other from Sweden, who are on a quest to leverage design principles to improve the lives of impoverished people. After almost 2 years of preparation and fundraising, they are finally on their way. Their goal is to meet with local communities, villages, governments, etc, to identify ways where design can improve the lives of the people. Traditionally, design is expensive, and therefore inaccessible, to poorer people. But, Design For Africa has a goal to find ways to solve problems with cost effective solutions. It will be interesting to see what they come up with; but, check out the site, and read their Diary.
