Mono Wave — 3D AI Start-Up Landing Page

A complete, scrollable aI start-up landing page with the 3D built into it: a monochrome ribbon of 90,000 lit particles drifting like smoke. It is one self-contained HTML file, built entirely in code, with no image files, no 3D models and no build step. Under the hood: Three.js, one particle sheet shaped and lit entirely in the vertex shader, additive grain, scroll-driven twist. What a visitor can do: move to tilt the wave, scroll to wind it tighter, 4 presets (Mono, Sand, Ice, Paper). Best for: AI agents and automation tools, developer platforms, consultancies, minimal SaaS. Three.js loads from a CDN through an import map and the type (Instrument Serif, Inter) from Google Fonts, so there is still nothing to install. The page is real HTML — a navigation bar, a full-height hero, content sections, a call to action and a footer — so the brand name, headlines and cards are edited as plain text. Colours, counts and speeds sit in a CONFIG block and a PRESETS array, colour themes restyle the page and the 3D together from a small swatch pill, ?embed hides the pill and ?tour scrolls the page by itself.
