/shameless plug - In my defense I originally read the title as "..you have done.." vs "..you have seen done.."
Two of my OSS projects are Bash and I'm rather proud of them:
A pretty cool shell-centric template engine:
* https://github.com/TekWizely/bash-tpl
* Has full bats tests to confirm compatibility with Bash 3.2 onward
* Makes heavy use of Bash regexes
A wrapper over update-alternatives that enables user-level configurations:
* https://github.com/TekWizely/my-alternatives
* Versions for Debian, SUSE, and RedHat
* Supports per-shell level configurations as well
