## What it is
Field Play is a browser-based WebGL application for exploring and visualizing vector fields by animating thousands of GPU-driven particles. Users write GLSL formulas that define the velocity at each point, and the app renders the resulting particle flow in real time.

## Use cases
- visualize vector fields with animated particles in the browser
- experiment with GLSL formulas to create particle flow art
- teach or explore vector field mathematics interactively
- generate beautiful generative art from math equations
- share vector field visualizations via URL parameters

## When to choose
- you want an interactive, GPU-accelerated vector field explorer with zero setup
- you want to prototype velocity field equations in GLSL and see particle motion instantly
- you need a visual teaching aid for vector calculus or dynamical systems

## When to avoid
- you need programmatic access to vector field data or numerical solvers rather than visualization
- you need a headless or server-side rendering tool
- you need support for 3D vector fields or non-WebGL environments
