## What it is
Blotter is a JavaScript library for rendering unconventional text effects in the browser using GLSL shaders through WebGL, without requiring designers to write shader code. It renders text into canvas elements with a shared WebGL context and texture atlasing for performance.

## Use cases
- create animated text effects for website headings
- apply GLSL shader effects to titles without writing GLSL
- make playful stylized text graphics for landing pages
- render distorted or liquid text animations in the browser
- build creative typography for design portfolios
- add channel-split or distortion effects to hero text

## When to choose
- you need eye-catching animated text for titles, headings, or graphic elements
- you want shader-based text effects without GLSL expertise
- you prefer a lightweight library over heavy animation frameworks for typography

## When to avoid
- you need selectable or accessible body text - Blotter renders to canvas so text is not selectable
- you need long paragraphs of styled text
- you need a library with active development and recent releases

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, graphics, ui-components
- domain: web-development, frontend, graphics
- platform: browser
- tags: webgl, glsl, typography, text-effects, creative-coding, shaders, javascript
