If you're a fan of tigers, dragons and Japanese symbols then YingYang LCD could be the download for you.
The theme features an image of a tiger and a dragon wrestling with a ying and yang symbol as the main background wallpaper. I'm not really sure what the symbolism of this is - to me it just looks like something someone would have tattooed on their back.
The tiger/dragon image in YingYang LCD is set against a black background with some gold bars running across it. Unfortunately, this background obscures some of the data on the home screen, such as network provider, messages, and application shortcuts.
YingYang LCD also tweaks some of the other Windows Mobile settings, altering the color scheme of the menus to a gray, red and white affair.
I couldn't decide if YingYang LCD was cool, or just a bit gaudy. Either way, it makes for a striking theme for your Smartphone.
