^0^ This tooks so fun! I don't think it's too late... this looks like you can even set it up last minute. The only question is if "someone" is going to do it, or if the con is? If it's a group effort, I'd be glad to type up the rules and we can hand them out at the con as adds. Prizes I think should be organized by the con, and if anyone is interested I've got a good suggestion for what should be inside the barrel if it's a ninja thing. Should someone else make the barrel, maybe a staffer?
