If you want to make your phone look a little more pretty then the White Abstract Flowers theme could be just the ticket.
This elegant Series 60 theme transforms your phone's home screen with a wallpaper consisting of some beautiful hand-drawn flowers on a white background. The White Abstract Flowers theme also adds a series of new icons to your system's menus. Although these aren't hideous, I found them to be a bit drab.
Anyway, if you want a bit of floral decoration for your mobile then the White Abstract Flowers theme is worth a look.
