Peer Review Prep'

I've made a few boards to help explain my practical proposal in tomorrows peer review. I've kept it pretty simple, partly because I'm at a point where I can't talk about it much more - I need to get on and start making it, and partly because they don't need to hear every bit of information I have gathered on the topic.
In the meantime, I am going to make a really early mock up of the book, so I can show them the content I am proposing, which will hopefully help structure the feedback. I'm mostly concerned about my (lack of) ideas for the activities, so I'll see if anybody has any suggestions.
