I am very happy with what we got, as I wrote in another comment. I still find it strange that the author would go out of his way to write the article, produce screenshots, write multiple times how it's hard to explain or show without an animation, yet not record one.
Asking whether I'm willing to provide my own gif isn't quite a fair measure. The author has the code running and he himself commented on the need for moving pictures. I have partial code and no personal investment in this.
I have however written a few articles about stuff I've done for my own work and wherever it seemed relevant I've taken the time to produce and include video. That's been a lot less effort than writing the text, even when it's required a number of changes in the scenes and code.
