## What it is
TremulaJS is a client-side JavaScript UI component for building Bézier-path-based content streams with momentum and physics effects, supporting mouse, scroll, and touch interactions. It is essentially a highly customizable image carousel with cover-flow-like stepped scrolling.

## Use cases
- build an animated image carousel with physics-based momentum scrolling
- create a cover-flow style gallery where items snap to center
- add touch-friendly scrolling picture streams to a mobile web page
- render content along custom Bézier curve paths
- build a horizontal scrolling image grid with scroll and drag support

## When to avoid
- you need a modern, actively maintained library with recent updates and security patches
- you want a lightweight simple slider without physics or Bézier path features
- your project requires a permissive license since TremulaJS is GPL-3.0

## Facets
- artifact type: library

- function: animation, ui-components, frontend-framework
- domain: frontend, web-development, graphics
