Desktopia is a customization concept for Mac OS X. Thanks to it’s very simple and unobtrusive interface you will be able to configure desktopia to automatically change your desktop picture based on a specified time of the day. For example a beautiful sunrise at 7:00AM or a starry sky at 10:00PM. Just drag & drop the pictures that you have chosen on desktopia’s window, set the time, and voilà!
