It can be easy to forget that Earth is not the center of the Universe and that there are billions of other stars and planets out there.
Install the 30 Doradus Theme and it'll be a constant reminder of the insignificance of our small planet. In case you didn't know, the 30 Doradus is a large star formation complex in the Large Magellanic Cloud. The main background wallpaper in this free theme, taken from the Hubble Space Telescope, shows just how beautiful this constellation is.
Aside from altering the background image on your Today screen, the 30 Doradus Theme also alters the colors of the top and bottom menu bars, and applies a reddish transparency to the Start menu, in keeping with the colors in the main image.
If you're a keen astronomer then the 30 Doradus Theme will be the star of your Pocket PC.
