The Code School team recently released a course called Rails 4: Zombie Outlaws. While Rails may not be of much interest, the UI is full of decisions made to follow a narrative.
Justin Mezzell, Jason VanLue and Nick Walsh will be discussing how this went from concept to implementation. If you want to check it out, you can play the first level for free to get a feel for the UI that we will be discussing. http://rails4.codeschool.com/levels/1
