Backgrounds
13 full-bleed animated backgrounds — original shaders, particle fields, and cursor-reactive surfaces in molten forge tones. Every tile below is the real component running live; each one pauses offscreen and respects reduced motion.
The signature pro background: a viscous molten-bronze shader with amber crest highlights, ember-red troughs, a slow violet iridescence sweep, and a cursor heat-welt that swells the metal. Original OGL fragment shader, offscreen-paused and reduced-motion-safe.
A physics pit of molten-metal spheres that tumble in and settle under a heat glow. Instanced rigid bodies, bloom, pointer stirring, offscreen-paused, and reduced-motion-safe.
A scroll-scrubbed tempering shader: white-hot amber turbulence at the top of the page cools through ember red into blued violet-steel with oxidation bands — and scrolling back genuinely reheats. GSAP ScrollTrigger drives an original OGL fragment shader, with idle micro-motion, custom phase keyframes, and a static mid-temper frame under reduced motion.
A foundry sky: three parallax layers of spark-stars in warm white, amber, and rare red over nebula smoke lit from below in ember and violet, crossed by occasional downward-falling sparks with gravity-bent trails. Mouse and scroll parallax, offscreen-paused, reduced-motion-safe.
An audio-reactive furnace: a horizon coal bed whose glow and flame-lick height follow amplitude, with bass strikes hurling ember volleys upward and treble adding spark flicker. Degrades to a gently breathing coal bed without audio — never black. Mic capture only behind an explicit user gesture, with full AudioContext and GL teardown on unmount.
Crucible's signature aurora: ribboned bands with a moving metallic sheen on a near-black field, in molten forge tones. Original OGL fragment shader, offscreen-paused and reduced-motion-safe.
An iron-filing field: a grid of short segments aligning to a slow magnetic-dipole field when idle and bending toward the cursor, warming from gray-violet steel to molten amber. Original OGL fragment shader, one draw call, offscreen-paused and reduced-motion-safe.
A field of glowing embers rising from below in molten forge tones, each with its own phase, flicker, wind drift and color ramp; the cursor stirs a gentle updraft. Original OGL fragment shader, offscreen-paused and reduced-motion-safe.
An interactive dot grid: rivet-head dots warm violet → ember red → amber as the cursor approaches, with a configurable falloff curve. Freezes to a static, gently warmed frame under prefers-reduced-motion.
A synthwave perspective grid reimagined as a forge floor: a near-black plane receding to the horizon with ember-red scrolling grid lines, a molten-amber furnace glow, and an optional slit-scanned horizon sun. Pure CSS, SSR-safe, honors prefers-reduced-motion.
A falling-spark background: steep, hot streaks decelerate and die mid-air in an extinguish flicker, with the occasional spark forking into a second briefer ember. Pure CSS, seeded PRNG for deterministic spawn layout, honors prefers-reduced-motion.
A slow-drifting gradient mesh background. Pure CSS, zero dependencies, SSR-safe, honors prefers-reduced-motion.
Animated film-grain / noise overlay: fine, warm-biased metal-dust speckle that blends over any content via low opacity and mix-blend-mode, with an fps throttle for a slow, smoldering look.
