ASCII Field
A live ASCII field: a light spot typeset in glyphs from a dot to @ breathes and drifts like on a terminal. GPU-rendered, zero dependencies. For dev tools, hacker products, CLIs and indie games.
What you can change
- speed — still, calm or lively; still draws a single frame with no loop
- intensity — faint, soft or bright: the accent strength; soft by default so the background does not fight the content
- cell — small (12px) or large (18px): the glyph size
A link for your AI agent: preview, code and instructions.

Technical notes
One file, zero dependencies, "use client". A WebGL2 fragment shader on a single triangle, simplex noise (Ashima, MIT). The palette is CSS variables with light-dark; the shader reads them through the canvas computed border-color, so theme, accent and colors work identically for the canvas and the CSS fallback. Paused outside the viewport and in a hidden tab (IntersectionObserver, visibilitychange), prefers-reduced-motion and speed=still draw a single frame, without WebGL2 the radial-gradient fallback stays. Theme switches are caught by a MutationObserver on <html>. Palette --vibeui-surface-014-*.
