There is this "Art in Transit" project that got funding to put little 28"x11" placards in Pittsburgh city buses with art on them instead of the usual advertising. The deadline was just yesterday, so I scrambled wednesday night to put something together, cheating a little bit by reusing some of my old material from the screenprinting stuff I had done before. Still I'm pretty happy with it:

I can't help but plug Tom's submission to the same project also. It's great.
