## What it is
A simple, lightweight 2D physics engine written in CoffeeScript, featuring Verlet integration, particle behaviors like attraction and collision. It is designed for browser-based creative coding and interactive demos.

## Use cases
- simulate particle physics in the browser
- add simple physics to a canvas animation
- create interactive particle demos with mouse attraction
- learn how a Verlet integration physics engine works
- build lightweight 2D physics effects for web pages

## When to choose
- you need a tiny, easy-to-understand 2D physics engine for browser demos
- you want simple particle behaviors like attraction and collision without heavy dependencies
- you are doing creative coding or teaching physics simulation basics

## When to avoid
- you need a maintained library with active support
- you need rigid body dynamics, joints, or 3D physics
- your project is in modern JavaScript or TypeScript and you cannot use CoffeeScript-era code

## Facets
- artifact type: library
- maturity: abandoned
- function: simulation, graphics, animation
- domain: graphics, web-development
- platform: browser
- tags: physics-engine, coffeescript, verlet-integration, particles, lightweight, game-development, javascript, web
