Truchet Pattern Studio

This app turns a 300-year-old idea into an endless pattern machine.

In 1704, Sébastien Truchet noticed that a single square tile, dropped onto a grid in random rotations, produces patterns that never repeat and never stop being interesting. Truchet Pattern Studio gives you that grid, and then gives you every dial worth turning.

Tap Shuffle. Watch arcs braid into ribbons, wedges snap into a Bauhaus poster, waves roll across the canvas. Every pattern is generated from a seed number, so anything you like can be saved, reopened and rebuilt pixel for pixel.

WHAT YOU CAN MAKE

- Ten tile sets: arcs, chevrons, slashes, wedges, petals, waves, rings, circuits, weave, scales
- Density from a bold four-tile grid to a fine 42-tile mesh
- Line weight, stroke caps, margin and chaos — turn chaos down and order emerges
- Filled tiles for solid, poster-like colour blocking
- Twelve palettes, from ink-on-paper to neon grid, zellige and copper plate
- Colour modes: one ink, scatter, checker or a sweeping gradient across the grid

EXPORT

- PNG at square, portrait or phone-wallpaper size
- Set any pattern as your home and lock screen wallpaper in one tap
- Share straight to any app
- True vector SVG for print, laser cutting, embroidery and design work
- 3× HD renders and large formats up to poster size

BUILT FOR DESIGNERS AND TINKERERS Seeds make everything reproducible. The gallery stores your patterns as parameters, not images, so they reopen fully editable. Presets give you twelve tuned starting points when you would rather begin from something good than from nothing.

Advanced FEATURES

- Multi-scale subdivision — tiles split into smaller tiles, recursively, for dense fractal weaves
- Symmetry: mirror, flip and kaleidoscope
- Live shuffle — tiles rotate and re-settle on their own, hypnotically
- Gradient and transparent grounds, plus film grain
- Four extra tile sets, four extra palettes, three extra studio themes
Vector SVG export, 3× HD export, unlimited gallery
