From the Phone Story website:
Phone Story is a game for smartphone devices that attempts to provoke a critical reflection on its own technological platform. Under the shiny surface of our electronic gadgets, behind its polished interface, hides the product of a troubling supply chain that stretches across the globe. Phone Story represents this process with four educational games that make the player symbolically complicit in coltan extraction in Congo, outsourced labor in China, e-waste in Pakistan and gadget consumerism in the West.
Keep Phone Story on your device as a reminder of your impact. All of the revenues raised go directly to workers' organizations and other non-profits that are working to stop the horrors represented in the game.
