Says Björk: “The Biophilia Educational Program is a new way to teach children about science and music. It has met with success in many cities, sparking interest from kids and educators from all over the world, from South America to East Asia to Africa. The most interest has come from students from low-income households and schools with underfunded art budgets, and the only way to bring the project to those people is to have Biophilia reprogrammed for Android and Windows 8. The Biophilia educational project is strictly non-profit and volunteer-based, and that’s why we need your help.”
