I'll take any questions about those comics sometime later as i like food and bed very. Briefly though, I'd gotten so slackbrained about the concept of revision, I thought it would it be scientifically prudent to make revision comics. About six hours per module, mostly in one sitting. These were originally intended for my eyes only but became much more interesting than that. Please do not rely on these as a study aid, although if they make fun learning they've worked beyond what they were meant for.
