Draw, tune, and export the classic figures of sacred geometry: Vesica Piscis, Seed of Life, Flower of Life, Metatron's Cube, and the Golden Spiral. Every figure is constructed from circles and straight lines only - no images, no libraries.
Patterns
- Vesica Piscis - two circles, each passing through the other's center. The almond-shaped overlap (the mandorla) holds the square roots of 2, 3, and 5, and every figure below is built from it.
- Seed of Life - six circles around a seventh, each centered on the rim of the last.
- Flower of Life - the Seed continued outward on a triangular lattice, from 7 circles up to 127.
- Metatron's Cube - the thirteen circles of the Fruit of Life with all 78 lines joining their centers, holding the flat shadows of the five Platonic solids.
- Golden Spiral - Fibonacci squares laid corner to corner, with quarter circles approximating the logarithmic spiral that grows by phi (1.618...) every quarter turn.
Controls
- Depth - rings, circles, or squares, depending on the pattern
- Rotation - 0 to 360 degrees
- Stroke - hairline to heavy
- Palette - Gold, Moonlight, Rose Quartz, Jade, Spectrum, Ink
- Background - Midnight, Void, Parchment, or transparent
- Construction lines - show the scaffolding each figure is built on
- Animate - watch the figure draw itself, stroke by stroke
- Surprise me - a random pattern, palette, rotation, and weight
Exports
Save SVG and Copy SVG give you true vectors, so they scale to any size for print, laser cutting, plotting, or embroidery. Save PNG renders a 2048 x 2048 image. A transparent background exports with no backdrop at all.
Under the hood
Plain HTML, CSS, and JavaScript building SVG through the DOM - no dependencies, no build step, no tracking. Each pattern is defined in patterns.js as a function returning shape descriptors in unit space, so adding a new figure means adding one entry to that array.
