According to wikipedia, "the term public art properly refers to works of art in any media that have been planned and executed with the specific intention of being sited or staged in the physical public domain, usually outside and accessible to all." Wikipedia mostly pointed to large, imposing works to illustrate examples of public art. Baltimore's own "Man/Woman" statue came to mind.
At the artbomb party, we had a table full of paper scraps, glue, markers, brads, paper clips, envelopes, and all kinds of found objects and tools. Mary has done a lot of public art, and explained that public art can really just be something you make for others to find. Whether you're yarnbombing or hanging up posters on the street, you are giving your gift of art to anyone who just happens to see it. A public art project could be something people see and smile about, something that makes people think, or something that people can take with them, add to, or share with others. The possibilities are endless, as they say.

Here are some pictures of what we made:
