Whenever I've watched this, I've stopped it several times and just tried to think of/like the people in the audience. What were they thinking? What previous and familiar techniques and technologies were they using as the lens to see this through? If you had them brainstorm in small groups about how they could use this if they had it for the next year, what would they think it was good for? Is it something they saw as useful for themselves or just for record-keepers and report writers?
