Subway, underground, metro mapped: iPod

iSubwayMaps offers reference images to bring along on your portable media player the next time you find yourself on an unfamiliar subway sytem.

Toronto's subway system is a cinch running mostly along one east-west line and two north-south lines. There really isn't a need for carry-on cartography, but bringing along a subway map sure is a fun idea when it's sitting on an iPod.
