Subway Map Artist Draws Every City From Memory - r/MapPorn

An artist posted a timelapse of himself drawing London, Tokyo, New York, Paris, and Berlin subway maps entirely from memory with remarkable accuracy, claiming he memorizes transit systems as a form of travel preparation. The r/MapPorn post hit 43,000 upvotes and attracted transit authority employees in the comments who identified only seven minor errors across all five maps. Three major transit authorities reached out offering commission work, and a separate r/IWantToLearn post asking how to develop similar memory skills hit the front page the following day.
