In January 2014 a teenage design student from Slovakia named Martin Vargic posted a map of the Internet — inspired, he told The Independent, by the xkcd classic — on his DeviantArt page. The map quickly went viral. Since then, he’s been producing maps of all sorts of things — a revised Internet map, a literature map, historical maps, maps of the world after global warming and an ice age, a stereotype map (see previous entry), plus other infographics — at a dizzying pace, most of which are available for sale on his website. Now his maps are being collected in a book, Vargic’s Miscellany of Curious Maps. It’s out now in the U.K. from Penguin imprint Michael Joseph; in North America it’ll be available in December from HarperCollins. Did I mention he’s a teenager?
