iTerm2 has a basic animated cursor that I like, just a frame or two long, and fairly subtle. It would be nice if it expanded to support this type of animation, I do wish it were a bit more visible (though not, perhaps, the EDM show presented)

This (OP) project is inspired by neovide, a recent neovim gui. And iterm2's animated cursor is a brand new feature, also inspired by neovide.

Honestly, iterm2 is way too nice a piece of software considering the price. A real labor of love from a guy who apparently has lots more free time than me. :-)
