Ofnuts beat me to it with more information. So a all-in-one screenshot.
This spiral came from Inkscape, no idea of properties, conveniently came out as almost 1500 px. You might have your own method of dividing the path up into equal portions, probably Ofnuts has a plugin for that as well. A bit of fiddling with brush size / brush spacing and stroke the path using the pencil tool.
