Comprehensive NYC transit map

This is pretty cool. Someone has tried to combine all the various transit services in the NYC metro area on a single diagram (not a scale map), in the fashion of the London Underground diagram. The standard maps from the various transit services (MTA, NJ Transit, Port Authority) generally only show you their own services, so it's useful to know -- for example -- that you can drive in from the Jersey burbs, park your car near the Lincoln Harbor development in northern Hoboken, take a Hudson-Bergen Light Rail car to Hoboken station, then catch a PATH train to Herald Square for some shopping at Macy's, then hoof it over to Penn Station for Amtrak to anywhere.

Could've used this a week or so ago.
