RandomWallpapers

Random geometric wallpaper generator. The generator has different modes (currently 'circles', 'squares', 'stripes', 'triangles'), which produce different image styles. Visually appealing color palettes are retrieved from http://ColourLovers.com.

Requirements

• python-cairo (install with sudo apt-get install python-cairo on Debian/Ubuntu systems)
• python-numpy (install with sudo apt-get install python-numpy on Debian/Ubuntu systems)
• python-scipy (install with sudo apt-get install python-scipy on Debian/Ubuntu systems)
• python-colourlovers (install with sudo pip install python-colourlovers)

Usage

./wallpapergen.py [--width VALUE] [--height VALUE] [--mode MODE] 
                  [--palette PALETTE] FILE

positional arguments:
  FILE            Name of generated PNG image file

optional arguments:
  --width VALUE   Width of generated image
  --height VALUE  Height of generated image
  --mode MODE     Type of wallpaper to generate; 
                  values: 'random', 'circles', 'squares', 'stripes', triangles'; 
                  default: 'random'
  --palette PALETTE  Color palette to use. Numerical palette id from
                  Colourlovers.com, or 'random'; default: 'random'

You may want to run the generator at regular intervals to constantly get new wallpapers. On a unix/linux system, this can achieved via a cronjob or the watch command line tool, e.g.

watch -n 600 ~/RW/wallpapergen.py --width 1920 --height 1080 --out ~/RW/wallpaper.png

This command assumes that you have cloned the repository to ~/RW, that your screen resolution in 1920x1080, and that you want to generate a wallpaper every 600 seconds. The reulting image ist stored in ~/RW/wallpaper.png which you can set as your desktop wallpaper. Any respectable desktop environment should reload the wallpaper as soon as the file changes.
