The Christmas Night 'enhancement' theme is actually a conditional overlay that can be applied to any of the themes to turn day into Christmas night. It is very similar to the Night enhancement, but adds a glowing North Star, moving clouds, and streaking 'falling stars'. The image above, as an example, is the starting Black Hills Theme with the Christmas Night enhancement applied.
