I published an article on the visual iconography of Occupy Wall Street over at the Comparative Media Studies website.  It’s by no means exhaustive — I focus on the Pepper Spray Cop meme and Guy Fawkes masks — but it was fun to write.  I’m thinking of writing a longer article just focusing on the use of Guy Fawkes masks in protests, sometime in the future when I have five free minutes strung together.  Check it out!
