p5.js Skill

Production pipeline for interactive and generative visual art using p5.js.

What it does

Creates browser-based visual art from text prompts. The agent handles the full pipeline: creative concept, code generation, preview, export, and iterative refinement. Output is a single self-contained HTML file that runs in any browser — no build step, no server, no dependencies beyond a CDN script tag.

The output is real interactive art. Not tutorial exercises. Generative systems, particle physics, noise fields, shader effects, kinetic typography — composed with intentional color palettes, layered composition, and visual hierarchy.

Modes

Mode	Input	Output
Generative art	Seed / parameters	Procedural visual composition
Data visualization	Dataset / API	Interactive charts, custom data displays
Interactive experience	None (user drives)	Mouse/keyboard/touch-driven sketch
Animation / motion graphics	Timeline / storyboard	Timed sequences, kinetic typography
3D scene	Concept description	WebGL geometry, lighting, shaders
Image processing	Image file(s)	Pixel manipulation, filters, pointillism
Audio-reactive	Audio file / mic	Sound-driven generative visuals

Export Formats

Format	Method
HTML	Self-contained file, opens in any browser
PNG	`saveCanvas()` — press 's' to capture
GIF	`saveGif()` — press 'g' to capture
MP4	Frame sequence + ffmpeg via `scripts/render.sh`
SVG	p5.js-svg renderer for vector output

Prerequisites

A modern browser. That's it for basic use.

For headless export: Node.js, Puppeteer, ffmpeg.
