## What it is
A collection of interactive WebGL sketches built with three.js by Yoichi Kobayashi, showcasing creative shader and particle effects like water, glass, fireballs, and flow fields. The repository is no longer maintained, with newer experiments moved to a separate site.

## Use cases
- learn webgl shader techniques with three.js
- find creative coding examples for particle effects
- reference implementations of water and glass shaders
- study flow field animations in the browser
- get inspiration for interactive web graphics

## When to choose
- you want well-crafted three.js shader examples to study or reuse under MIT license
- you need visual reference for creative WebGL effects

## When to avoid
- you need an actively maintained library or production-ready framework
- you require compatibility with modern Node versions or current three.js APIs
- you need a reusable component library rather than standalone sketch code

## Facets
- artifact type: learning-resource
- maturity: abandoned
- function: graphics, animation, developer-tools
- domain: graphics, web-development
- platform: browser
- tags: threejs, webgl, creative-coding, shaders, glsl, interactive-sketches, demo-gallery, game-development, web-server, nodejs
