Blob Lamp
9 glowing metaballs slowly rise, sway, merge and split through a violet-magenta-amber color ramp on a dark canvas — lava lamp in canvas pixels.

When to use it
Dark-mode hero backgrounds, psychedelic/creative portfolio sections, ambient looping screensavers needing organic blob motion.
When not to
Light-background layouts (background hardcoded dark). Low-end mobile — CPU-bound pixel loop runs every frame. Contexts needing legible overlaid text.
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Change blob count to 12 (N=12), shift the ramp amber stop to cool teal (#80ffea) at index 1.00, and slow rise speed range to 0.010–0.020. 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
- blob count (N=9)
- rise speed range (0.018–0.048 in bv[])
- color ramp stops array
- pixel block size (SC=4)
- swirl warp amplitude (0.06)
- theme tokens (:root dark defaults + [data-theme=light] overrides)
Keep intact
- low-res offscreen grid pattern (critical for perf)
- visibilitychange pause/start
- reduced-motion one-shot static frame
- IIFE wrapper
- theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
Known limitations
- CPU-bound pixel loop — heavy on low-end devices at SC=4
- Light re-theme via the [data-theme=light] token block; catalog bg/accent describe the dark default
- No pointer interactivity — fully passive
