One wallpaper across every display, built by eight people

macOS gives every display the same wallpaper, so a wide photograph turns into three copies of itself. I wanted the picture.

It is free and MIT licensed, and there is nothing being sold today. The work happens on your Mac and GitHub hosts the downloads.
