I have started doing this for my training courses. When I demonstrate live, I commit to git. I use some variation of "FAILING" in the commit messages to call attention to "red" commits, in "violation" of the usual rule that tests pass 100% in all commits.

azundo, I know my examples aren't web apps, but do you have time/energy to explore any of the branches in this code base[1], read the commits, and give me feedback on how easily you follow it?
