Over spring break I saw some interesting graphics in the JFK airport. Rather than using simple signage to direct travelers to different lines, they used colored circles on the walls to direct people along different passages. I don’t know if this is stretching it with information design, but “wayfinding” graphics seem very related. Here is an article that (among some other aspects of airport beautification) addresses the idea of wayfinding graphics in airports. It is interesting to see that graphics are viewed as a solution to current dissatisfaction with airports.
