The is a font made from public domain SVG's. The designers deserve all of the credit. I'm just packaging the SVG's into fonts. It's derived from the MapBox Maki, the AIGA, and the National Park Service icon sets.
Check out the README for usage instructions. It also includes instructions on how to add your own icons to it and create your own version of the font.
