As you can see on the Exeter Cathedral Facebook page:
"Andy Robertson will be facilitating an interactive video game throughout our worship where together we will enter a virtual creation and bring our own touch of transformation to it."
The service will make use of the PlayStation 3 game, Flower. The plan is that it will be played collaboratively by the congregation while the game’s music will form the background for other elements of the service. The controller will be passed around while other parts of the worship continue, and then brought to a conclusion as the first level of the game is completed.
