StarfishJS (like its C predecesor) is Free/Libre Software, and is licensed under the GNU GPL (version 3 or later).
The image generators all operate in monochrome values, and translated into color later. Some of the generated images aren’t displayed directly, but instead are used to hide/reveal pixels of other layers.
Installing the web interface for StarfishJS is as simple as:
$ git clone https://github.com/micahcowan/starfishjs.git
Then just point your web browser at the included
index.html file, and
you're good to go!
The best way to install the command-line tool, is to use npm. First, install NodeJS, then run
$ npm install -g starfishjs
to install the command (which is named starfish). (You might need to run the command via sudo, depending on how your NodeJS installation is set up.
Options: --help, -h Show help [boolean] --output, -o Path of the image file to create [string] [default: "output.png"] --size, -s Proportions of the output image [string] [default: "384x384"] --verbose, -v Display progress [boolean] [default: false] --version, -V Show version number [boolean] --wallpaper, -w [EXPERIMENTAL] Set the finished image as the desktop background [boolean] [default: false] Examples: starfish.js -v -s 720x720 (Or just -s 720.) The -v option is recommended for interactive use in a command console. starfish.js -o ~/wallpaper.png -w Generate a wallpaper at ~/wallpaper.png, and set it as the current desktop wallpaper. Currently, there are a number of known issues with this feature, including that it can't set tiled mode (so it'll be either centered or stretched - ugly if it's much smaller than the desktop); and doesn't set all desktop backgrounds, only the current one.
