I recycled the class that used Aristotle's Poetics as a foundation for persona development, and hence for improving the drama of SCA (see the April 13, 2009 post). I presented it to a couple dozen people at Warriors and Warlords, Northshield's "big event". I added some visuals using a flip chart. Projectors don't work as well as I'd like in a pavilion on a beautiful sunny afternoon.
Of course I plugged the Challenge -- especially the persona development track.
