The island is the latest of a series of MacArthur-supported projects carried out over the past two years to explore the power of virtual spaces for social good. They include a number of MacArthur-hosted events in virtual worlds on a range of issues from human rights to community development. With MacArthur support, the University of Southern California held a community challenge to identify new projects that promote the public good in the physical and virtual worlds. Winning proposals were each awarded 100,000 Linden dollars (Second Life currency equivalent to approximately $400 USD) and a plot of land in Second Life to build their projects. On the teen platform of Second Life, MacArthur grantee Global Kids worked with the Chicago-based Field Museum on “I Dig Tanzania,” a project to engage young people in paleontology. Most recently, the Foundation supported the Field Museum in launching WhyReef, a virtual reef to help teens understand marine biodiversity while building science literacy.
