Sundance Film Festival: Gaming meets film in Iran revolution

As well as showcasing the best in independent cinema, the annual Sundance Film Festival is trying to show how state-of-the-art moving image technologies can be used to tell stories in very different ways.

As part of the New Frontier section at this year's Sundance there is an installation that puts festival goers in the midst of the 1979 Iranian revolution as participants.
