# Wandering Eyes

> Wandering eyes loading animation

A Loader component for React, Tailwind and shadcn by @turbostarter, version 1.0.0, MIT licence.

A loading animation with moving eyes that simulate natural eye movement and blinking. It renders two eyes that move and blink in a continuous loop. Use it for loading states where a more human-like animation is desired.

## Install

```bash
npx layro-cli add @turbostarter/wandering-eyes
```

Or with shadcn: `npx shadcn@latest add https://layro.dev/r/turbostarter/wandering-eyes.json`
