Transit card art

I'm a huge fan of all things transit. I love subways, trains, schedules, stations, tokens, and transit cards. I dream of someday having a subway car in my house. What? It can serve as a hallway or maybe it can be a small den. I do a lot of my reading during my commute, why not read in a stationary subway car at home? One can dream...

I created some "art" out of my transit passes - I wish I had enough to cover an entire wall! What's the most interesting transit pass you have?
