This map shows all trains on the London Underground network in real time, in the style of the map in Skyfall after seeing they had a version of my original map :-)
I have a (per-station) National Rail version, and an awesome bookmarkable train times journey planner.

Live departure data is fetched from the TfL API, and then it does a bit of maths and magic. A small number of stations are misplaced or missing; occasional trains behave oddly; some H&C and Circle stations are missing in the TfL feed.
