The document discusses public space and different types of art in public spaces including street art, graffiti, and vandalism. It includes opinions from students that street art can enhance public spaces when done appropriately but can also cause problems if unwanted. Students discuss how the line between street art and vandalism is blurry and depends on the viewer's perspective and location of the art. They also debate how public spaces are meant for everyone to enjoy and some feel street art allows for free expression, while others associate it more with graffiti and feel it can make some users of public spaces feel unsafe or left out.
