Microsoft demonstrated their new Smart Glass tech today at E3. And sure, it's cool that you can watch a video on your iPhone, iPad, Android phone, or computer, tell it to pause, and resume seamlessly on your Xbox later.

But what's really cool? Having an interactive map of Westeros pop up on your phone, tablet, or PC while you're watching death and destruction in the War of Five Kings onscreen. Good luck beyond the Wall, Jon Snow!
