The New York City-based collective ArtCodeData has created a marvelous mash-up map covering 214 international metro/subway systems. The fanciful map represents 791 real lines, 11,924 stations, 214 urban centers, on 5 continents all connected in a single map. The project is a current Kickstarter which will offer various versions of the completed map. A non-profit group called Open Accessibility is selling the maps to finance projects facilitating travel for people living with disabilities.
