I reverse engineered Apple's video wallpapers

Phosphene is a developer tool that lets macOS users replace Apple’s native video wallpapers with custom videos by reverse-engineering the system’s wallpaper engine. It’s built for developers and power users who want full control over their desktop aesthetics, offering a way to bypass Apple’s locked-down format. The project is interesting because it reveals how Apple’s video wallpapers work internally and provides a technical workaround for a feature that was previously unmodifiable.
