Well, I created them one year ago using Fireworks. I didn't understand the importance of saving them in .svg back then. Now I do :-) I'm planning to export all the vectors to Illustrator, then saving them in .svg, then putting them in Github too.
You didn't seriously trace all maps in Fireworks, did you? Do you realize you can download shapefiles for all countries from multiple places on the net, and then render them at all desired sizes and styles with an afternoon worth of programming?
Yeah - I've been really dumb on this one, I know :-)
Turn them into .svg, then load them all into http://icomoon.io/app/, and release it as an icon font set.
