Here are a number of font icons I've generated that are free for all to use. Ideally, I would love to see these one day included in some of the great projects such as @fontawesome, But ultimately that's for them to decide. Feel free to use any of the icons in this repo.
I use fontello for generating the font files from the svg files. They done a fantastic job letting you generate your own webfonts from a number of different fonts around the community.
