New WorldChanging contributor Cameron Sinclair has been awfully busy with his group Architecture for Humanity, and it's in a pretty damn good cause. Wired News has an interview with Cameron up today where he talks about his latest big project: the Siyathemba design competition, looking for designs for a combined soccer field and health-care facility in Smokhele, a community in KwaZulu-Natal, which has one of the highest HIV/AIDS infection rates anywhere. It's an inspiring project, and we're proud that Cameron is a worldchanger (in every sense of the term).
