Here is a IMO very large collection of spinner-like unicode animations: 

https://asciinema.org/a/ex8z3z6d5m7uv4buww0o2qeq2 

This comes from Zsh world, it's a plugin with spinners to use in Zsh scripts. I've never managed to see even 1/3 of them.

Yes git config setting of this is most convenient IMO, most expected to occur in ~/.gitconfig, in which it would be set once to a favourite gauge-box script, and rather long long before looking at this part of config again. Or maybe in the beginning, dawn of such gauge-scripts (if there actually would be any new group of such scripts; but as it's a quite broad problem (see last `PS.' paragraph), then who knows), when some unstable gauge-box would be breaking login/passwords prompt (but that's stdout not stderr, shouldn't go through gauge-box-script) or "fatal: ..." messages, etc., user might be disabling it temporarily or choosing an alternate gauge-box solution, editing the config option ;) So not rarely edited in the beginning. (I don't know how much important would a fancy gauge box be for a regular user; I can tell it would be quite important to me). I think this is more convenient and clean than `export GIT_*' in .bashrc/.zshrc, rarely edited, just sitting there. 

Guys you seem to like the idea, I hope someone will approach the coding! 

PS. There's much room for improvement in the git-process-output.zsh in the Asciinema video, gauge scripts won't be simple. In general, the number of 0..100% sequences (like: compressing, resolving, etc. – they all go 0 to 100% on their own) should be somehow predicted (does Git know this in advance?) and the gauge should be divided into that many segments, each filling up per one corresponding 0..100% sequence, together forming single global 0..100% gauge.
