Line drawings for pen plotters.
Pick a generator, shape it with the settings, and download an SVG sized in millimetres for your paper, with duplicate strokes removed and paths ordered to cut pen travel. Everything runs in your browser.
3D and terrain
Mountains
Noise-driven terrain drawn as a wireframe grid.
Wormhole
A wireframe tunnel that narrows to a throat between two mouths.
Boxes
A scattered pile of wireframe boxes, each sized and turned at random.
Ridgelines
Stacked profile lines where each row hides the ones behind it.
Contour map
Height lines traced across a noise landscape, like a topographic map.
Patterns
Voronoi
Cellular patterns from scattered, gridded or clustered points.
Tiling
A jittered grid of shapes, some of them hatched solid.
Truchet tiles
Square tiles turned at random so their curves join into long winding lines.
Circle packing
Circles that grow until they touch, drawn plain, as rings or hatched.
Maze
A solvable maze with square cells, with the route on its own pen layer.
