This page contains a series of logos I created in 2015 since the project didn't yet have one.
In 2021, I was asked if the following logo could be used on a new website for the project:
https://www.mingw-w64.org/
Since I'd lost the original SVG source, I re-created it and also gave it a repo with license to make it clear that the logo was free for use:
https://github.com/ratfactor/mingw-w64-logo
Here's the SVG:
Several of the logos have eight items, four of which are highlighted in a different color or luminance, representing the 8 bytes native to 64-bit architectures which differentiates them from 32-bit's 4 bytes.
The gnu heads are made from a handful of vector points and are thus...minimalist gnus, get it?
Those last checker pattern logos, in addition to having the 8 squares as mentioned, also look like a pair of overlapping ++s, which could be evocative of C++, arguably one of the more popular languages supported by GCC.
These are not "finished" or "professional" logos. They're just an amateur fooling around for an evening. Perhaps the community can come up with something it likes.
Perhaps this list will help get the creative portions of your brains going for logo ideas.
Yup.
