Follow this link to the video of the set up of the Keypeer Seeker Challenge held at the Children's Museum in San Diego for Comic-Con. Quite the amazing event for kids and adult. You were given a ball capsule with a riddle in it. You'd figure it out to open a locker in the next room. They weren't that tuff, thy wanted kids to get prizes. Prizes were a bunch of different AT goodies like pins and small toys. There was also an art gallery segment.
