## What it is
A tiny JavaScript demo that renders an animated 3D Christmas tree made of two spirals, inspired by a reddit post. It serves as a fun creative-coding example showing 3D projection and animation in very few lines of code.

## Use cases
- learn how to draw animated spirals in JavaScript
- example of 3D projection on a 2D canvas
- fun holiday animation for a website
- study a minimal creative coding demo
- port the tree animation to another language

## When to choose
- you want a small, well-known example of canvas animation and 3D math
- you need a festive animated graphic built in a few lines of code
- you are learning creative coding techniques

## When to avoid
- you need a general-purpose graphics or animation library
- you want production-ready, configurable visualization tooling
- you need accurate shadow rendering or extensible architecture

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: graphics, animation, data-visualization
- domain: graphics, web-development, education, entertainment
- platform: browser
- tags: christmas-tree, canvas, spiral, demo, creative-coding, 3d-projection, javascript, web
