But there's a GIF in the very first section of the README showing a bunch of different effects. What else is it missing?

Oh I guess it didn't load for me then. I was a bit surprised at the absence of it.

Consider my peeve unpeeved :)

I think they wanted an example of each animation in a list.

But I'm going to add my own nitpick and say that there shouldn't be any gifs. It's a wasteful annoying format. Use a video for it's smaller size, better visuals and it's ability to be paused/played/seeked. An asciinema would be nice too.
