## What it is
An open-source iOS demo application that interactively explores Apple's Core Animation API, covering layer classes like CALayer, CAShapeLayer, CATextLayer, and CAEmitterLayer. Each layer type includes live controls so developers can manipulate properties and observe the animation effects in real time.

## Use cases
- learn how Core Animation layers work on iOS
- experiment with CAShapeLayer and CAEmitterLayer properties interactively
- see examples of CATiledLayer and CAReplicatorLayer usage in Swift
- reference sample code for CALayer animations
- understand differences between Core Animation layer subclasses
- teach or demo Core Animation concepts to a team

## When to choose
- you're an iOS/Swift developer learning or teaching Core Animation
- you want hands-on, interactive exploration of layer properties
- you need small working Swift examples of various CALayer subclasses

## When to avoid
- you need a production animation library or UI framework
- you're targeting Android, web, or non-Apple platforms
- you need actively maintained code with recent updates

## Facets
