I think Folding@Home deserves to be known! I was looking for a "Support F@H" logo (or such) to add on my web site and I didn't found any. Perhaps I didn't search enough...
Anyway, the "Download F@H" and "F@H support forum" logos look great, but instead of using an image editing software to replace the text, I recreated the logo using Inkscape, in a vector format (SVG) so that I can use the size I want.
So what ? Well, I'm giving this (these) SVG conversion(s), hoping it (they) will be useful: http://sukender.free.fr/images/logos/fah/ . You'll see there SVG logos with or without text, and PNG exports of them. It's not perfect, but at least you can resize infinitely the SVGs...
I suggest to put these logos somewhere it can be found on the web site (in the "About us" page, perhaps?).
If you can see SVG (*), it looks like:
If not, here is a PNG export:
(*) Opera browser rocks
If you're using it, try zooming the page and see SVG-PNG difference...
