Maxwell J Roberts (who work this appears to be) is a Psychologist
researching in this area. He has produced a whole range of Underground
maps using different design methodologies. He even has a book on the
subject. Some of the designs in it are barely usable (and he produces them
to prove that very point) yet artistically appealing.
