-Each morning women in Tamil Nadu, in southern
-India, place designs, created by using rice
-flour and known as kolam on the thresholds of
-their homes.
-
-These can be described by Lindenmayer systems,
-which can easily be implemented with turtle
-graphics and Python.
-
-Two examples are shown here:
-(1) the snake kolam
-(2) anklets of Krishna
