Samuel Arbesman has done a map of the Milky Way in the style of Harry Beck’s London Underground map. “I have attempted to actually make this map as accurate as possible, where each line corresponds to an arm of our galaxy, and the stations are actual places in their proper locations. However, I am not an astronomer or astrophysicist, so there are certainly inaccuracies, gaps, and room for improvement.” Quite possibly the most out-there take on the Tube map I’ve yet seen, if you’ll pardon the expression.
