nov17b is based on the code by Matt Pearson
on his book "Generative Art", page xxii, stuff about 2D noise. The effect of his original sketch is available on the top banner of his personal website. He also has a project called 100 Abandoned Artworks
which includes all the source codes of examples from "Generative Art".
I modified his code and produced two high resolution static outputs as well as a video.
