No, this did not happen to me. I did like the idea, though, and I wouldn`t put it past some of the conference organizers/volunteers. The past three days or so have been totally done digitally. My skills with the pen are improving, but it`s still a long way from “good”. I did notice that my strokes flow better, but I think I may try a thinner brush over the next few days. I really liked doing the four-panel thing, and having the two in the center be “free-form”. I may use that more often when I want to get “dialogue-y”
