Global Sharknado Threat and other adventures in mapping

I've been a fan of cartographer John Nelson's for a few years now. I featured some of his work in The Truthful Art and now, thanks to Jonathan Crowe, I've discovered that he has a blog with detailed mapping tutorials. In it, John explains how he made the peculiar projection of his now famous historical map of hurricanes, or this map of Global Sharkando Threat, while dropping nerdy asides here and there (Star Wars as a stylistic influence!)
