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?
