XS Pack 100

I've decided to brush off my good old XS style and rebuild it on a 16 pixel grid. These are the first 100. Later on I will probably add a couple of hundred more. In the package you'll only find the ai vector file. Please let me know what I should include as well. Separate 16px, 32px and 64px PNG files? SVG files? Perhaps even an icon font? Just a little market research : , untill then these 100 pixel perfect vector icons will only cost $9.
