This seems to be the source she is referring to: https://github.com/tqh/haiku-efi/tree/master/src/libs/icon/flat_icon https://github.com/tqh/haiku-efi/tree/master/src/libs/icon/f..., specifically the FlatIconFormat class. Some of the most interesting deconstructions and experiments have come out of The Recurse Center, great learning experiences and blog posts by these students. I found the concept of the format interesting in how it meets the goals of being modern (a vector format) while staying slim for disk reads (optimizing the format specifically for icons). Lastly the usability aspect is tackled by creating an icon editor specifically for the format. In the creator's blog post, he notes that creators might not be able to take full advantage of the format because they might not know how the it works, but I think it's fine since the format constrains the palette anyway.
