I'm not very techy oriented and I am sort of alone in these studies up here in copenhagen, so, maybe someone knows how to do an equivalent thing (or point me for the start) - how to record frame after frame from history (now I know what pages to look for - but how to make it movie'ish?!). The idea is that, although History Flow can well show the changes, it is difficult to get a good grip - looking first at a movie would/could give a lot of insight. Also, for public presentations - would be nice to have some easy movies to show what is happening.

Jon used screencasting software to make that movie. First he made a screencast flipping through each version, in order. Then he made a screencast of PLAYING BACK the first screencast both forwards and backwards. Clever guy, that Jon.
