I am planning to add the possibility to control the radius of the circle, but for now I just made a quick conversion of the original COFFEE code into Python.
<file removed>
Edit: Just to point out, the original COFFEE script is not mine.
I don't want to take credit for this plugin, just provided a rewrite into Python.
Edit 2: I have removed the script file in this thread, as it has now been uploaded into the download section of the forum.
