If you consider yourself more of a night owl than an early bird then this Space Theme could be for you.
The free theme adds an eye-catching background wallpaper to your phone, and features a glowing blue moon and some kind of bright green light (which could be an alien, I guess) against a black background.
Besides this striking wallpaper, the Space Theme also adds a stylish new analog clock to your home screen, and also applies a revamped color scheme to your S60's menus. Unfortunately it doesn't add any new icons though.
If you're amazed by the night sky, then prepare to be fascinated by Space Theme.
