To follow on the discussion of public art in Minneapolis, here's a cool St. Paul project I had somehow missed.
The Everyday Poems for City Sidewalks project works in tandem with St. Paul’s sidewalk maintenance program and installs poetry where city sidewalks are replaced. The cost of the art installation is negligible, since the material has to be laid anyway. A stamp, inspired by contractor's stamps, impresses the text into the wet concrete.
In its first year, the project had the goal of one hundred stampings of twenty poems written by St. Paul residents, chosen from 2000 submissions.
