nice, i may have to look into using these for my personal css framework project. i'm still not sold on svg as an unalloyed good over font icons (as they're really verbose and cluttery in markup), but they do have some good points as well (e.g., multi-color and css-able).
To me, the key point about having the SVGs is they're basically the "source code". Whether you want to use SVGs directly or not, you can, and you have all of the tools to make high-quality custom icons using the same shapes.
