The United Nations Human Settlements Program (UN-Habitat) has a mission to create or improve 300 public spaces in the developing world by 2016. This led them towards Mojang in Sweden and their game Minecraft.
The partnership that spawned from this is called "Block by Block", which uses Minecraft to help teach young people in the planning of urban public spaces. Haiti, Nepal, India, Rwanda, and Kenya are countries undergoing projects with the help of said program.
