Forgeplot

Make generative art that a pen plotter can actually draw. Forgeplot turns simple sliders into intricate line art built for pen plotters. Pick a style, tune it by feel, and export a clean, ready-to-plot SVG — correctly sized for your machine, organised by pen, and optimised so the pen takes the shortest path. Not plotting today? The same piece exports as a crisp wallpaper at the exact size of your iPhone, iPad or Mac. Everything is real single-stroke vector art, built that way from the ground up. No raster tracing, no import-export juggling, no code. THIRTY-FOUR GENERATORS, WITH MORE IN EVERY UPDATE • Fields & flow — Flow Field, Topo Contours, Ridgelines, Warp Grid, Moiré • Growth & organic — Differential Growth, Space Colonization, L-System Plant, Fractal Tree, Particle Trails, Flocking • Packing & mesh — Circle Packing, Voronoi, Dot Field • Tiling & symmetry — Truchet Tiles, Wave Collapse, Subdivision, Mandala, Maze • Curves & lines — Harmonograph, Lissajous, Spirograph, Superformula, Space-Filling Curve • From your photos — Hatched Photo, TSP Portrait, Stipple, Halftone, String Art, Low-Poly, Squiggle • Simulations — Reaction–Diffusion, Cellular Automata, Strange Attractor BUILT FOR REAL MACHINES • Presets for AxiDraw (A4, Letter, A3, SE/A1, MiniKit) and iDraw, plus any custom size • True physical sizing — a 210 mm piece measures 210 mm in Inkscape • One layer per pen, in drawing order — plot one colour at a time and swap pens between layers • Colour By: every generator can split its lines by what they mean — trunk and canopy, old and new growth, tile orientation, tone — so a two-pen plot says something • Path optimisation that typically cuts pen-up travel by 90% or more • Hidden-line removal and multi-pass for ink saturation • Plot preview: watch the pen path and see time, ink and stroke count before you commit ONE PIECE, EVERY SCREEN • Export wallpapers at your device's exact resolution — iPhone, iPad, Mac, 4K, square • Recompose regenerates the piece to fill a new shape instead of cropping it • Ink-on-paper or inverted YOURS, EXACTLY • Every piece is saved as a recipe — generator, seed and settings — so it reproduces identically, at any size, forever • A personal gallery on device; nothing is collected, nothing is tracked Pen plotters connect to a computer over USB, so Forgeplot exports and hands off: AirDrop to your Mac or save to Files, then plot from Inkscape (with the AxiDraw extension) or saxi.
