Forgeplot · generative art, plotter-first

Make generative art that a pen plotter can draw — or that lives on your screen.

Forgeplot turns simple sliders into intricate, hand-drawable art. Pick a style, tune it by feel, and export a clean file ready for your pen plotter — or the same piece sized perfectly for your iPhone, iPad, or Mac wallpaper. Every design is real single-line vector art, built from the ground up to be drawn with a pen.

No code. No import-export juggling. Just make something and draw it.

How it works

Three steps from idea to ink

Each style is a living generator, not a filter — move a slider and the whole piece redraws itself instantly.

01
Truchet-tile pattern of connected arcs, an example generator style in Forgeplot.

Generate

Choose a style — flowing fields, packed circles, growing coral-like lines, geometric tiles, or turn a photo into a single continuous line. Each one is a living generator, not a filter.

02
A branching, coral-like differential-growth line drawing, an example generator style in Forgeplot.

Tune

Drag the sliders and watch it change instantly. Tap the dice to explore. Use Apple Pencil on iPad for fine control. When you find one you love, it's saved by its recipe, so you can always get it back — exactly.

03
A topographic contour-line drawing, an example generator style in Forgeplot.

Export

Send it to your pen plotter as a ready-to-draw file, or save it as a wallpaper at the exact size of your screen. Same artwork, either way.

Save it as a wallpaper or print

Every piece also exports as a crisp image. Pick a size, choose Recompose to fill the shape exactly or Fit to keep the plotter composition, and save straight to Photos. Because the art is true vector, it's razor-sharp at any size — and a wallpaper always matches its plotter twin.

Tips for great plots

A few things that make a real difference

  • 01 Start simple.A single-pen piece on plain paper is the fastest way to a great first result. Add colors and complexity once you know your machine.
  • 02 Match the pen to the setting.Fine liners (like a 0.3–0.5 mm Micron) suit detailed work; set the pen width in the app so shading and hatching space themselves correctly.
  • 03 Good paper matters.Smooth, heavier paper (marker or mixed-media stock) drags less and bleeds less than copy paper.
  • 04 Watch the plot time.Dense pieces (fine hatching, TSP portraits) can take a while — the plot preview shows an estimate before you commit ink.
  • 05 Save the recipe.Loved a result? It's stored by seed and settings, so you can plot it again later at a different size or on different paper — identically.
