TITLE: GLYPH RAIN — matrix cascade, refined PROMPT: Design 'GLYPH RAIN', a matrix-style cascade refined into art: streams of glyphs (mixed katakana, digits, symbols) falling at varied speeds, but composed — density waves and synchronized columns create rhythm rather than noise; occasional bold 'message' moments where a phrase flickers across. Palette: near-black with phosphor green plus rare amber accents. Interactions: typing injects your characters into the rain; pointer movement attracts streams; a DENSITY slider from drizzle to deluge; a PALETTE chip set (green, amber, ice, bloom-pink); click for a radial burst that scatters columns. Iconic, disciplined, luminous. DESCRIPTION: A disciplined Matrix-style cascade on near-black: glyph streams of mixed katakana, digits, and symbols fall at varied speeds with density waves and synchronized column rhythm rather than noise; bright lead glyphs fade into phosphor trails, with rare bold "message" phrases flickering across the field. Phosphor green by default with amber accents; typing injects your own characters into the rain; the pointer attracts nearby streams; a density slider runs drizzle to deluge; palette chips re-dye (green, amber, ice, bloom-pink); clicking fires a radial burst that scatters columns; prefers-reduced-motion composes a single still frame with trails then stops. TECHNIQUES: column-based glyph particle system with per-column speed/phase, density wave modulation, leading-glyph brightness with alpha trails, typed-character injection into falling columns, pointer attraction field, radial burst impulse on click, palette chip theming, reduced-motion static render. INTERACTION: Type to seed your glyphs into the rain; move the pointer to attract streams; click for radial bursts; drag density; switch palettes.
