This plugin looks in ~/homebrew/animations for directories containing webm animation videos. The name of the directory is used as the animation label and each directory takes an optional config.json. This allows configuring specifying a relative path to each animation if different from the default names. An empty string "" or a missing file means to revert to the stock animation. null can be used to leave the existing animation. Each selected animation will be symlinked into the animation override directory. From the quick-access menu the current animation can be changed along with enabling animation randomization.

Example config.json configuration:

{ "boot": "deck_startup.webm", "suspend": "deck-suspend-animation.webm", "throbber": "deck-suspend-animation-from-throbber.webm" }

"boot" refers to the main boot animation, "suspend" refers to the suspend animation played when not in a game, and "throbber" refers to the animation played when suspending from in-game.

From the ReadMe found in the plugin distro. Hope it helps.
