Playpower uses a $12 TV-computer (TVC) as a platform for open-source participatory design of 8-bit learning games that will improve educational access for millions of children in the developing world and create real economic opportunities for adults. The TVC uses an existing TV as a display and is based on an 8-bit video game processor technology that is now in the public domain due to expired patents. Playpower is working with partners in Brazil, Ghana, India and the United States to build an open-source Software Development Kit from which local organizations can create their own learning games.
