+#### Yeah I know, this is called sketch_2020-09-06flat but the URL is missing the -09
+
+
+The base for this "glitch" is a fork of (@aparrish) Allison Parrish's amazing example using Flat + Bezmerizing to draw SVG.
+
+Lot's of help from Marco Macarena adding the HTML inputs!
+
+This version uses a single flask route, generates and inserts the SVG inside the HTML it serves, a second optional route generates just an SVG.
