Sorry! I know this discussed as part of our world domination, but it looks like no one got back to you. As far as I know the raster image is the best we have so vector would be very welcome if you would care to share.
The first attachment in my previous post is a *.svg image. Unfortunately I couldn't upload it with *.svg extension, so I've changed it to *.gif (but the filetype is of course still SVG).
This is the source file I created in Inkscape. Unforunately I know only very basics of vector graphics, so I don't know how to achieve this hand-painted effect which you can see on the raster image nor how to add some more details to it.
Hope someone will help, as I think that the vector version of Code Ranch logo might be useful in the future :-)
