This script draws a “Gingerbread man” fractal. The shape is generated by applying a simple iteration and plotting the x,y values. It has an extra function which keeps track of the distance between successive x,y points in the iterations, this is used to derive the color of the points to make the fractal look more interesting visually. It uses the kandisnky and math libraries. Tested on the calculator using software version 23.2.6.
