Probably a year or so ago, I made this design and submitted it as a possible Ubuntu Women t-shirt:(download SVG source—you'll need the old Ubuntu Title font to render the SVG properly)
Today I requested SVGs of the new logos popping up around the *buntusphere, and Martin Owens had them all so went and modified my design. I think it's beautiful!(download the SVG source —you'll need the new beta Ubuntu font to render the SVG properly)
He added flower petals around the logos, now that they're all perfect circles, and he even added a FLOSS flower to it! Love it! Lyz is looking into getting t-shirts made with this on it and how the Ubuntu trademark stuff factors in. Finally, Martin turned this into a really nice wallpaper:
All of the above is CC-BY-SA, but it's still subject to Canonical's Ubuntu trademark rules thanks to the Ubuntu logo in there.
