This is a collaborative project between myself and Greg McInerny of Microsoft Research. We have worked together (Greg doing all the programming and gathering of data, and both of us working together on the visual aspect) to visualise the insertions/deletions of text through the six editions of The Origin of Species, by Charles Darwin. (More information to follow)
