This is neat. Dumb question, but one I think a lot of your clients will have: how easy is it to drop one of these sets into Bootstrap and have them work the same way Glyphicons do?
Works almost exactly the same way. Fonticons also has all the extra features Font Awesome has -- larger sizes, icons in lists, flipped, rotated, animated. And you can pare that CSS down to be just what you need, too. Speed, speed, speed.
