Peter Suderman, whose movie reporting and reviews I also enjoy, linked to a video on the London Underground map.
The map, of course, is extraordinarily lucid in its execution and also in its conceptualization.
Aside: Mrs. FLG likes the names of the lines, particularly Jubilee. FLG likes the chilled Cadbury Creme Egg dispensers.
The influence of the London Underground Map is undeniable. Almost every other transport system in the world's map is a knockoff. Moreover, it undoubtedly influenced the development of FLG's favorite board game -- Scotland Yard.
