Renders columns of falling characters that cycle through random glyphs each frame, recreating the iconic digital rain effect. Built with useCurrentFrame() and useVideoConfig() for frame-perfect column timing. Use as a full-screen background behind titles, intros, or tech-themed content.
Adjust character set, column density, fall speed, and color. The effect is fully deterministic — every frame produces the same output — making it safe for server-side rendering and reproducible across runs.
