One thing that's essential if you're going to celebrate the holidays properly is a tree. But if you can't have the real thing then why not install one on your phone with this Christmas Tree theme.
The tree in question here is more of a modern artistic representation of a tree rather than the traditional kind you normally think of. The white squiqqly tree is set against a blue background and is displayed not only as the wallpaper but also in blurred form behind the Series 60's menus.
The Christmas Tree theme also alters your system icons and while these new white, stencil-style buttons look classy, they're not particularly Christmassy.
If you don't mind flying in the face of festive tradition, the Christmas Tree theme gives your phone a cool wintery feel.
