I made an origami gnu based off some origami instructions I found online. Possibly suitable as an alternate logo. Looks vaguely similar to the Clear Linux penguin, but not as polished or polygonal.
I'm not an artist and this only took a couple of hours. Please tweak and use under whatever license you prefer. Or don't use. It was done purely for fun in inkscape.
Sorry about the imgur link. I'm unsure what you prefer for sharing pngs.
