Standalone generators and utilities for creating plotter-ready SVG artwork.
Generates a wandering-ribbon typographic poster from Beatles lyrics using the Relief SingleLine plotter font.
On first run, lyrics are fetched from tylerlewiscook/beatles-lyrics on GitHub and cached locally to .beatles_lyrics_cache.json (gitignored). Subsequent runs use the cache.
python tools/beatles_typography.py # defaults
python tools/beatles_typography.py --font-size 8 --png # with PNG preview (requires cairosvg)An image to squiggle converter primarility designed to make interesting portraits without the usual cross-hatch or fill methods. It attempts to draw squiggly lines to make the shading instead. Code generated using several prompts and codex / GPT.

Perlin noise landscape generator adapted from turtletoy.net. Requires the turtletoy npm package.
cd tools && npm install
node tools/perlin_landscape.mjs -o landscape.svg
node tools/perlin_landscape.mjs --lines 400 --panels 6 --seed 42Generates SVG calibration grids for testing shading/fill patterns. Produces a grid where rows are pattern types (hatch, crosshatch, dots, circles) and columns are density levels.
python tools/calibration_grid.py -o calibration.svgConverts swisstopo GeoPackage layers to SVG for pen plotting.
