I've always said that I should make a tumblr for my students to access links/photos/ideas/articles that I discover online and that are relevant to their class. I teach grammar, literature, and 1st year writing classes.
The title of this tumblr is a quote from Samuel Beckett's play, Waiting for Godot.
Shephard Fairey is a graffiti artist whose popular “obey” sticker, he hopes, will make its viewers reconsider the world around them. He supports “grassroots efforts to change the world for the better” and has showed his support for the Occupy movements. Read about that here. Here’s Shepard Fairey’s official website. You may want to look at some of Fairey’s work or graffiti in general and see how it could be interpreted as art that supports people who are not in positions of power and may help them to speak out.
