This theme is ideally suited for semi-fantasy themes. A word of warning, however, it would be more suited to smaller windows, as the image stretches and distorts on the bitmap for larger windows.
This fantasy themed windowskin has the background of an awesome silhouetted dragon set against a fiery sky. The frame and interface is reminiscent of modern times but with a subtle fantasy flavor.
There are currently no examples yet, but there will be soon.
