Lec_32: Draw a cross-stitch curves with a single pen| Recursive Python/Turtle Function

This tutorial presents a recursive construction of the Cross-stitch curves.
1) Presents algorithm of the recursive Cross-stitch curves.
2) Presents an efficient Python turtle graphics code for the algorithm.
3) Shows Cross-stitch curves with different turning direction.
Try to to draw with different turning angles and enjoy the resultant Cross-stitch curves.
