Comic-book conventions are wonderful spectacles of geekery, and major Cons are the only place to get exclusive access to behind-the-scenes previews and sneak peeks at your favorite comic book or upcoming film. But for us, the biggest attraction at these sweaty gatherings is the Cosplay: fearless nerds showing off their love for genre characters with marvelous homemade costumes. This past weekend, we roamed the halls of San Francisco's Wondercon to play Cosplay paparazzi. The cosplay harvest wasn't as bountiful as last year's San Diego Comic-Con (where we snapped up four hundred photos ), but we still found some delightful gems (and familiar faces) at this local event. Keep an eye out for no fewer than four Rorschachs from the upcoming Watchmen movie, sexy slave Leia, and the most amazing Transformers costume we've ever seen!
