Fresh Wallpaper

A Node.js command-line tool that continuously generates fresh desktop wallpapers using AI-powered image generation models on Replicate.

I use this with OBS to create background images on the fly during video calls and screencasts.

Features

• Generates images from a given theme
• Sets the system desktop wallpaper
• Saves all generated images to disk (default: ~/fresh-wallpaper)
• Saves a copy of the latest generated image as _latest.webp (so you can point OBS to that file)
• Adds MediaProvenance metadata to downloaded images so you have a record of the model, input, output, etc.

Installation

npm i -g fresh-wallpaper

Create a Replicate API token and set it in your environment:

export REPLICATE_API_TOKEN="r8_..."

Usage

fresh-wallpaper <theme> [options]

Options:
  --image-model <model>  Specify the image model to use (default: 'black-forest-labs/flux-schnell')
  --output <directory>   Specify the output directory for images (default: 'outputs')
  --interval <ms>        Specify the interval between image generations in milliseconds (default: 1000)

Examples

Basic usage:

fresh-wallpaper "bananas dressed up like cowboys"

Using a different image model:

fresh-wallpaper "ZIKI the man dressed up like a cowboy" --image-model "zeke/ziki-flux:dadc276a9062240e68f110ca06521752f334777a94f031feb0ae78ae3edca58e"

Use a custom output directory:

fresh-wallpaper "bananas dressed up like cowboys" --output "my-images"

Generate images every 5 seconds (instead of 1 second, the default):

fresh-wallpaper "bananas dressed up like cowboys" --interval 5000
