Art by me (@kriblo). Code is also by me, but it's mostly art. Main image is made up of polygons, filled with one of eleven different colors (see inside for palette). There is also a version with black lines, or stroke (this version emerges after 10 seconds). Both were made in the Scratch Vector Editor, but the stroke was altered in Notepad, replacing 'stroke-linejoin="miter"' with 'stroke-linejoin="round"', to avoid pointy corners (or vector thorns). I started out with kriblo from the project "Rubber kriblo": https://scratch.mit.edu/projects/1138473082/ I call it "pop art", but I'm not an arts expert ;)
