Hi Matt,
Member "ShishaPipeUK" did a very nice Christmas snow and lights mod a couple of years ago - see

This could be a good place to start as an alternative to doing a full out Christmas skin (or used jointly with if you want to go overboard
) - hope is useful !!!
This is only one I ever remember seeing in the forums myself (apart from your red ideas
) - cheers, Asiaplay
