Circles and sticks was the way i was taught to write, when i was a kid. I do not know how it is done nowadays. Made some examples illustrating figures you can do with the simple little font.
In addition you can watch the whole project on my deviant-art page where you can find the font in vectors, in case you cannot install fonts, and some free png characters.
P.S. uploading this font to any other site is forbidden. Only redirecting links to this page are allowed.
