I'm a little surprised that nobody else has suggested that there might be a way that control of this little app might somehow be given to CK5. That's what I want to see; the whole crowd part of the light show. I agree that the way it is now cell phones are a huge distraction at shows. I just don't think we're going to get people to turn them off or leave them home if they can't even stop talking on them when they're driving. So, maybe if they're using this app they're at least participating, instead of distracting the people behind them trying to shoot uwatchably shaky video.
