If you're lucky enough to be going to this year's Comic-Con, that is: Steve Purcell, winner of the 2007 Eisner Award for Best Digital Comic and creator of all that is psychotic bunnies and (cool) anthromophic dogs, is going to be there. It's the same Purcell you're thinking of, as evidenced by the official site. (Also, clicking on that link will kill your dial-up; there's a LOT of pictures.)
The event takes place at San Diego, so if you happen to live in the area and yet manage to not go the Convention and write a sonnet about Steven then keep in mind that you deserve to die. Also your feet smell funny.
