A group of video editors are given a shared set of assets and a few different challenges (no animation, use only still images, same b-roll from an iPhone, keep it under 1:00, use only creative commons licensed materials for anything additional, etc). Those editors sit in a public location (maybe in the conference room) and have their screens projected while they edit for an hour (?) prior to the session presentations, (perhaps with a moderator providing Iron Chef style play-by-play?). The participants then discuss their thoughts in general about editing and storytelling, and the works are presented, questions are answered.
Anyone game for being a part of it? It would all be in the spirit of fun and not harshing judging your chops. I'd down to be a moderator, announcer, or editor and hand over the reins to anyone.
