Code replay animation

[falcaopetri]

Suppose we have tracked a problem's solution through out a dojo session (#90)... How can we highlight how much the hands-on, multi-pilot, TDD experience contributed to the final code state?

Imagine something like this:

half_the_frame_size.mp4

I've used https://github.com/meowtec/diffani/ to render the output. There's room to improve transition duration, some indentation, coloring, video aspect etc. But I wanted to validate the idea and gather the opinion of the maintainers.

In the future, I also imagine a side-by-side test suite section, i.e., show the tests at the right side, with custom animations whether they passed or failed.

I'd also love to use a Python library, but diffani and all other similar apps I found use a node/react stack.
