The topic we decided to use is super heroes and super villains and the visual clues to both identifying, creating, and outfitting one or the other. Some of the ideas we had would be to focus on the history of the comic book and the use of color to depict meaning, an exercise in creating their own comic storyline, character design elements and visually telling some of the character's back story, as well as allowing the students to make up their own super and design a signet for that hero.
We have not decided what the students will print yet but we narrowed it down to three ideas centered around their signet design- either a signet ring, a shield with a crest, or a hood ornament for their character's vehicle. I think that this will be a topic that all of the students will know something about and that many students will be interested in participating in.
