From the developer:
KonaBot is an application that auto updates your desktop wallpaper with Konachan images. Inspired by Irvue, KonaBot is a Mac application that downloads images from Konachan.com and set them as your desktop wallpaper regularly. You can set from Preferences the desired auto update interval.
