A Project using the data from the Boston Subway System - MTA

I was in Boston yesterday, and the group that I was in ended up talking about the Boston Subway system called the MTA. We ended up talking about projects that have used the recently opened up Data on the MTAsystem. One of the best visualizations I have seen on the system is by Mike Barry and Brian Card on Github. I provide the link here for all those who want to enjoy their work.
