These are only meant to help for cases where the full tux is too detailed to display, see examples in the linked README. But the shape also works well for single fill cases, like in the keychain example. I wouldn't want these to be used when the full tux could be displayed in all its glory instead.
One issue I have is I do not know how to license these properly, I wouldn't want them to show up in a trademarked logo or anything, but I would still want them to be freely usable as tux icons anywhere. What do you think?
I have chosen the CC BY-SA 4.0 license, thank you for helping me!
I think these either need the beak to be a bit irregularly shaped or needs a black line inside the beak to make it more clear this isn't just a big hole in the face but an actual bird beak.
But other than that its great! And that's of course just my personal opinion, you do you!
I can't find it, but I have seen a video where a designer talked about how you can't just invert your monochromatic logo to make it white-on-black. There's an effect that will make several aspects of the logo feel very differently, even though it's just inverted.
I think you’re absolutely right… perhaps something with the effect of lighter compared to the rest = open vs darker compared to the rest = closed.
I think it’s also magnified by the fact that we’re comparing to the full color one on the right which has the lighter color for (in my perception) open eyes.
Creative Commons is exactly the tool you need for licensing; they even have a "build-your-own" customized license tool. The tool will generate an icon, text, and a link to easily understandable legalese for your license.
CC is like GPL (but more flexible) for art, and it's an awesome service.
The beak looks like a wide open mouth. It does not look like a beak.
The middle icon colour scheme makes it look like it has a different expression to the other icons, like one of those squinting/extremely pleased anime faces. The expressions should match regardless of colour scheme.
Very nice icon, would you consider contributing it to font-logos project (where a lot of FOSS projects logos are, including Tux) that is used on nerd-fonts so people can use it on their terminals?
Nice to see SolveSpace being used for it. Edit: Fix typo.
I could see something like this being a common use icon, it's very well done. I prefer this look to having the big bodied Tux on a small icon, this solves the problem well. Good job!
