/*{ "DESCRIPTION": "Digital microscope micro-ecosystem. Fourteen large organisms — amoeba host, flagellates, ciliates, jellies, digital diatoms, darter symbiote, paramecia, volvox colony, a lobed medusa, a second amoeba and a giant drifting jelly — swim through multicolored plankton with streamlining bodies, bow waves and fluid wakes. Membranes warp constantly with traveling waves, breathing harmonics and drifting noise. A swarm of ten micro-fauna and eight round spike-protein viruses (15s infection cycle with green glitch corruption) fill the medium. Every 20s the host slowly stalks a victim, absorbs and dissolves it, and later the victim glides back out reborn. Diatom and darter live in symbiosis; others wrestle gently on contact. All under a lens with reticle, scanlines and barrel distortion.", "CREDIT": "CC0", "CATEGORIES": ["generator"], "INPUTS": [ {"NAME":"speed","TYPE":"float","DEFAULT":1.0,"MIN":0.0,"MAX":3.0}, {"NAME":"grain","TYPE":"float","DEFAULT":0.6,"MIN":0.4,"MAX":2.5}, {"NAME":"emit","TYPE":"float","DEFAULT":1.0,"MIN":0.0,"MAX":2.0}, {"NAME":"warpAmt","TYPE":"float","DEFAULT":1.0,"MIN":0.0,"MAX":2.5}, {"NAME":"wiggle","TYPE":"float","DEFAULT":1.0,"MIN":0.0,"MAX":2.5}, {"NAME":"hueShift","TYPE":"float","DEFAULT":0.0,"MIN":0.0,"MAX":1.0} ] }*/ #define TAU 6.28318530718 float h11(float n){ return fract(sin(n*127.1)*43758.5453123);

Digital microscope micro-ecosystem. Fourteen large organisms — amoeba host, flagellates, ciliates, jellies, digital diatoms, darter symbiote, paramecia, volvox colony, a lobed medusa, a second amoeba and a giant drifting jelly — swim through multicolored plankton with streamlining bodies, bow waves and fluid wakes. Membranes warp constantly with traveling waves, breathing harmonics and drifting noise. A swarm of ten micro-fauna and eight round spike-protein viruses (15s infection cycle with green glitch corruption) fill the medium. Every 20s the host slowly stalks a victim, absorbs and dissolves it, and later the victim glides back out reborn. Diatom and darter live in symbiosis; others wrestle gently on contact. All under a lens with reticle, scanlines and barrel distortion.

export clip · render a video in your browser
Renders to video in your browser (no upload), stepping the real renderer frame by frame so multipass + feedback come out right. motion auto-animates the shader's own knobs — each export rolls a fresh take (🎲 re-roll, 🔒 to pin one you like). GIF is slower with a tighter length cap; MP4/WebM are faster. Some devices record in real time (noted below if so) — keep the tab visible.
caps: ≤1920 per side, ≤60fps, ≤18000 frames (GIF ≤300)
