Complete engine for ASCII art, dithering, halftone, and character-based shaders over images and videos. 14 algorithms (Floyd-Steinberg, Bayer, Atkinson, blue noise, Riemersma, Stucki, Sierra, JJN), 40+ charsets, 9 art styles, WebGL/WGSL/GLSL shaders, CRT/bloom/glitch effects, color science (OKLAB), video pipeline, React components. Use when converting images or video to ASCII, applying dithering or halftone effects, building retro/CRT/terminal visuals, writing GPU dithering shaders, rendering braille or block characters, or any character-grid visual. Triggers on: ASCII, dither, halftone, error diffusion, character art, text art, retro rendering, stippling, blue noise, Bayer, braille, CRT, scanline, image-to-text, video-to-ASCII, mosaic.
