Symbolic Pastel Abstraction
Pendulum Diagram
A harmonograph rosette draws itself stroke by stroke in pastel hues, fades, then reseeds with new frequencies — evoking symbolic-abstract automatic diagrams.

When to use it
Dark-mode hero backgrounds, generative art displays, meditative ambient loops with an esoteric or spiritual visual tone.
When not to
Light backgrounds (hardcoded dark #1d1a24 fill). Contexts needing user interaction or legible text overlays — the constant redraw competes with content.
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Change the pastel palette to warm earth tones by replacing PASTELS with ['#d4a96a','#c97b5a','#e8d5b0','#b87333','#9e6b4a'], and slow the draw cycle by changing PERIOD from 9 to 14. 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
- pastel color palette (PASTELS array)
- cycle period (PERIOD=9)
- damping factor (P.d range 0.0016+0.001)
- frequency ranges (f1/f2/f3/f4 in newFig)
- rosette radius scale (A = min(W,H)*0.40)
- theme tokens (:root dark defaults + [data-theme=light] overrides)
Keep intact
- DPR-aware fitCanvas sizing
- IIFE wrapper
- prefers-reduced-motion guard (static single frame)
- visibilitychange pause/resume
- theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
Known limitations
- Background color hardcoded in CSS and JS fill — must change both to use a non-dark background
- Frequencies chosen randomly each cycle; no seed control, so output is non-deterministic
