English: Barnsley Fern colour-toned for natural leaf appearance

Own work
I took the Turtle-Graphics based Python code from the Barnsley Fern's Wikipedia page and adapted it to use Python's "Tkinter" GUI library instead. (This has been included in Python's standard library since Python 3.7 so no external libraries are needed.) This gave a higher resolution image, allowed me to finesse the colour map, and save the image in PNG format. Python code is below, Python 3.7+ interpreter or Pypy 3.7+ JIT-compiler is required.
