Fantastic, but unfortunately the source code is minified: https://github.com/txstc55/ugly-avatar, making it difficult to see how it was done and learn from or contribute to the project.
(Of course, those repos may have main pushed later as well, invalidating this comment too)
Nice of the author to share the code. Thanks!
Chrome makes it a bit more intuitive, since the tab is called Sources, then click into Page > top > ugly-face > src.
That said, I don't understand why the author didn't simply commit the source code into the GH repo, especially since it's fully retrievable anyway. Maybe there's some goal in doing that other than security by obscurity I'm missing, since they've followed the same pattern for multiple of their repos. It seems kind of anti-collaborative to me.
