Parametric Koch snowflakes

The Koch snowflake is a fractal curve which was first described by Helge von Koch in 1904. The sequence of Koch curves starts with a triangle and successively replaces each side with a new side with added triangle.

This OpenSCAD code uses functions from a larger tiling library based on the use of perimeter descriptions in the form of {sidelength, angle} and Turtle geometry to generate the corresponding polygon.

Due to limits on recursion, we are limited to order 4 curves but since these ha
