I don't generally bother with different wallpapers and themes but I happened across this very nice theme and decided it was time get all Christmassy:

This one displays just like real lights....very effective!!

There are 11 different backgrounds included in the theme, all are excellent. More information (including download) [url=http://browse.deviantart.com/?qh=&section=&q=blackboy993#/d31lmel:1mdqjnws]HERE[/url:1mdqjnws].
