A mockup of the terrain of 22Cans' Godus game due to arrive in September 2013. It's a god game, and players will be able to flick tornadoes across the landscape with a mouse movement or touch-screen swipe. 22Cans took advantage of the success of Curiosity -- and the fact that it could show text on Curiosity's cube -- to promote Kickstarter funding of Godus.
