He makes games and helps others to make games for a wide variety of learning contexts, from language learning to community action. He also helps produce ARIS an easy-to-use, open source, augmented reality game platform. Chris teaches classes involving mobile game design, and directs the Local Games Lab ABQ, a fancy name for supporting unfunded faculty, students, and community members to make games and other interactive experiences to develop new forms of meaning within their local natural, cultural, and educational environments.
