Illuminated is a WinterBoard theme available via Cydia. This is one of Doug’s favorites themes. It is similar to the Time of Day theme that I wrote about a few days ago. Illuminated also changes your wallpaper based on what time is it. However, I actually like the look of this theme a little more than the Time of Day theme and it changes more often. In the Illuminated theme, there are eight wallpapers which means they change every three hours. The wallpapers represent the time of day, displaying a sun or moon that moves around your iPhone or iPod Touch’s screen. See screenshots below.
