In the past I used videos, with talk, or without talk, to explain dynamic behaviour of projects.
Lately, when I thought it made sense, I switched to short snippets showing behaviour. And when short enough (seconds) to animated GIFs.

I don't really like the silent videos, but the silent GIFs in a story work for me.
Like Jupyter executable notebooks, this allows to show behaviour. It also makes blogs a bit "busy/alive" depending on taste.
Thoughts?
