# # Obfuscated code or piece of art?
#
# This short notebooks shows a few examples of Python code, designed to draw something, and shaped as what they will draw...
# ## Mandelbrot set
#
# This nice little code will write a visualization of the [Mandelbrot set](https://en.wikipedia.org/wiki/Mandelbrot_set), on the domain $[-3, 3] \times [-3i, 3i]$, for $1500 \times 1500$ points, as a Bitmap (written manually in binary).

#
# ## Penrose patterns
#
# This second nice little code will write a visualization of a [Penrose tiling (infinite pattern)](https://en.wikipedia.org/wiki/Penrose_tiling) to a PNG image, of resolution $2000 \times 2000$.
