## What it is
A generative art system written in Common Lisp, providing 2D/3D vector math, an undirected graph data structure, random number utilities, and SVG output for creating algorithmic artwork. It is the successor to weir/snek and the predecessor to the author's newer 'auxin' project.

## Use cases
- generate algorithmic art in Common Lisp
- create SVG vector graphics for pen plotter drawings
- manipulate 2D and 3D graph structures programmatically
- explore generative algorithms with random distributions
- produce plotter art from code

## When to choose
- you work in Common Lisp and want a mature generative art toolkit
- you create plotter or vector art from algorithms
- you need a graph data structure tailored for creative coding

## When to avoid
- you want an actively maintained project - the author recommends the newer 'auxin' instead
- you need a turnkey art application rather than a programmer's library
- you don't want to manage a specific local dependency version (cl-veq v4.1.0-beta)

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, math, simulation
- domain: graphics, developer-tools
- platform: cli
- tags: generative-art, common-lisp, svg, plotter-art, vector-graphics, graph-algorithms, creative-coding, algorithms, linux, macos
