In 2012 I started a PhD in computer science at Inria, that I defended on the 8th of December in 2015.
It's entitled "Leveraging human-computer interactions and social presence with physiological computing" and you can get some background about the science behind on my website http://phd.jfrey.info/thesis/
As for all PhD, there is a manuscript associated with it, which weights (almost) 300 pages. It is a neat pdf file (https://tel.archives-ouvertes.fr/tel-01252152/en), but before that it was a neat text file that I had been writing using org-mode markup syntax.
The manuscript was versioned using git and while I was writing, a commit occurred every two minutes (I thanks https://github.com/nesquena/gitdocs for that).
Afterward the magic happened with a script which went through all 5379 revisions of the repository (~ 180 hours of writing) and created a 8K video collating each successive diff, 3 minutes at 30 FPS. The script could be used for any versioned text: https://github.com/jfrey-xx/textreplay
