## What it is
A Swift console application for macOS that creates dynamic wallpapers (.heic) introduced in macOS Mojave, from a JSON description and image files. It also includes wallpapper-exif for extracting metadata from existing dynamic wallpaper files.

## Use cases
- create a dynamic wallpaper for macOS Mojave from my own images
- build a time-based or solar-based heic wallpaper file
- extract metadata from an existing macOS dynamic wallpaper heic
- make a custom dynamic wallpaper that changes with light or time of day
- convert a set of images into a macOS dynamic wallpaper

## When to choose
- you want to create custom dynamic wallpapers for macOS Mojave or newer
- you need a lightweight command-line tool scriptable in CI or shell
- you want to inspect or extract metadata from existing .heic dynamic wallpapers

## When to avoid
- you are not on macOS, since dynamic wallpapers are a macOS feature
- you need a GUI tool for wallpaper creation
- you want to set or manage wallpapers rather than generate .heic files
