The different sections of our talk are arranged into a nominal 'chamber' shape, with the examples of successful escapes listed outside the walls for a little visual metaphor thing going on... [UPDATE: the presentation did used to be in a nominal chamber shape, but the one you see below is the latest version which has changed.] As we each took a section it was really easy to collaborate when putting this together -- we could basically assemble our own nodes (e.g I went away and thought about examples of Failure, then designed that section) and see the other person's contributions gradually assembling elsewhere.
