Incidentally if you want to explore non-verbal signalling I really recommend gibberish games from improv. Viv and I use them quite a lot in training (described here). I find that if you get people to practice setting up an activity in gibberish and then in normal language, they create a lot more engagement.

When facilitating, more and more I want to sense the next move at my fingertips
