My first glitch.com based sketch, visit https://sketch-2020-09-03a.glitch.me/ for new grids! The base for this “glitch” is a fork of (@aparrish) Allison Parrish’s amazing example using Flat + Bezmerizing to draw SVG.

I’m using a bizarre set of functions in flat_processing.py to make flat look like Processing Python mode I’m more used to.
