Generative Geometry

Poisson Disk Bloom

Gold Poisson-disk points bloom from center on dark olive, linked by a Gabriel graph. Each vertex flashes on arrival; click re-seeds, pointer plants new nodes.

When to use it

Ambient generative backgrounds, data-viz aesthetics, creative portfolio heroes where organic graph growth fits the brand.

When not to

Low-end mobile (CPU-bound edge draw). Contexts needing legible text overlays — additive blend competes with content.

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Change accent to cyan by setting ACC=[80,220,220], tighten spacing by changing the radius divisor from 13 to 9, and lower the cap from CAP=1100 to CAP=600. Theme: dark tokens live in :root, the light variant in :root[data-theme="light"]; ?theme=light or a {type:'forever:theme'} postMessage switches at runtime.

Safe to edit

accent color (ACC array)
spacing radius divisor (Math.min(W,H)/13)
point cap (CAP=1100)
bloom flash duration (age<46)
auto-reseed interval (t%140)
theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

CPU-bound per-frame edge traversal — perf degrades above ~800 points on low-end devices
Background color hardcoded in both CSS and canvas fill — must change both to retheme
Gabriel check scans only a 5x5 cell neighborhood; rare long edges may slip through on sparse layouts

Voronoi Shatter14 drifting sites partition the canvas into cool-blue Voronoi mosaic cells; moving the pointer nudges the nearest site toward the cursor.
Auto-MazeDepth-first maze carves itself wall by wall on a dark grid with shifting hue; a bright dot marks the active cell. Resets with a new color on completion.
Truchet Tiles8x8 grid of rainbow quarter-arc Truchet tiles that flip orientation in slow sine waves, weaving shifting interlocked curves across a dark background.
SpirographA hypotrochoid spirograph traced progressively on canvas with a shifting hue; each cycle completes then resets with new random radii and color.
L-System PlantAn L-system fractal plant grows branch by branch from the canvas bottom, swaying gently; clicking triggers a wobble and regrows a randomized plant.
Rotating Mandala12-fold mandala of 5 nested polygon rings that counter-spin, breathe in scale, and cycle through lilac-gold hues. Tap adds a spin impulse.
