This is the icon I've designed for the TINU software in the style of macOS Big Sur.
[TINU](https://github.com/ITzTravelInTime/TINU), recursive acronym for "TINU is not Unib***t", is a tool to create bootable macOS installers developed by [ITzTravelInTime](https://github.com/ITzTravelInTime). You can get the whole icon set by checking out the GitHub repo.
