"A deadly disease has broken out in your neighborhood, and it's your job to contain the disease!" That's how Apple's iTunes store describes the Dartmouth-built iPad app, Pox: Save the People. For 99 cents Pox shows gamers how disease spreads and the impact of vaccination on people. The goal: Stop everyone from dying. Pox is a creation of Tiltfactor, a lab started by digital humanities professor Mary Flanagan with a mission to create games that incorporate social causes and humanistic inquiry.
