Definitely check out the Papergirl bike project in Berlin. It is growing and should totally come to The Lou. Cool Hunting has a pretty good article on the project and it also tells you how to get involved.
If you love prints and bikes you'll love this project. It is basically a group of people focused on bringing free art to the people of Berlin (and other cities) via bike.
Although, Hotoff's goals are focused on free local news and the performative act of printing, Papergirl has been a great influence over the past week or so.
