In the Markdown Mark repository on Github, I had initially included only 12 static PNG images of the mark at different specific sizes. Several people asked me why I had done this instead of including a vector graphic, and the reason is actually extremely important. This is something everyone should know, especially people who are not designers.

They are all in vector and drawn on this page with Raphaël (don’t forget to zoom the page). I was thinking that they could be useful for other people and, although the design quality of icons is average, I am releasing them here under MIT licence.
