Cool, that repo seems to be missing the logo that's shown on the open pnp website. I'm assuming that that is the main logo since it's what's on the website.
Using the image from the website, and the SVG in that repo I recreated a vector version of the logo.
The font in the SVG file for the "open pnp" text is Futura Medium, so I downloaded that font. I set the website PNG to be 50% transparent and sized and lined up the text. The icon part of the logo was already in the SVG so I just used that.
I set up the logo in the portrait and landscape orientations on two separate pages in Inkscape. I expanded the paths of the text so you don't need the font installed. Attached are high resolution PNG files and the inkscape file of my recreation of the openpnp logo
I'm happy to add it back to the original github repo, but figured I'd post it here for now in case other people want it.
Thanks,
