Hi Ryles,

I've used the shift list component to good effect here. Step one is to reduce the list as the first and last points are the same. Then create vectors, based on a points previous and next point, to compare and then order a list based on their original position to get the most acute angle. And finally shift the list based on this new knowledge. There's one thing I haven't done in the definition below and that is to duplicate the first point at the end to make a periodic curve based on these control points.
