I don't know where else to start this, but would anyone be interested in doing a scripted cosplay chess performance? I'm looking for someone to help me organize it as well as a few cosplayers who can be in character. :) If you're interested send me a message!
Check out the Cosplay! Construction, tips, and advice topic. There's a similar cosplayer event, and they would probably be able to help you out with this.
Thanks! :)
