The Ancient Roman Subway
Here's a new addition to the list of things that aren't useful but are really awesome.
Statistics student Sasha Trubetskoy spent a whole lot of time and a huge amount of research skill to create this stylised and historically accurate subway map of the ancient Roman roading system as it appeared in about 125AD.
It's not going to be useful anytime soon but it does give a fascinating insight into how massive and well connected the Roman Empire was.
