Answer: The United Nations

In the fall of 2012, Mojang (the company behind the wildly successful sandbox building game Minecraft) announced they were partnering with the United Nations to use Minecraft to advance urban planning initiatives. How did the two organizations envision the project, dubbed “Block by Block”? In a press release on the subject, Mojang explained:

Just like the Swedish predecessor, “Block by Block” aims to involve youth in the planning process in urban areas by giving them the opportunity to show planners and decision makers how they would like to see their cities in the future. Minecraft has turned out to be the perfect tool to facilitate this process. The three-year partnership will support UN-Habitat’s Sustainable Urban Development Network to upgrade 300 public spaces by 2016. The first pilot project in Kibera one of Nairobi’s informal settlements is already in the planning phase

Through a combination of philanthropy, planning, and a little fun shuffling blocks around the expansive world of Minecraft, citizens the world over have a chance to remodel their environment with virtual tools.
