To make your SharePoint portal snow, add the following line into the <head> section of your master page:
<script src="http://s3.wordpress.com/wp-content/plugins/snow/snowstorm.js?ver=2" type="text/javascript" />
The unsupported easy way to do this is to simply open default.master located in TEMPLATE\GLOBAL and add it directly in there.
If you don’t want to link directly to the file on wordpress, simply save the .js file somewhere in your layouts folder and reference it like that.
Thanks wordpress for making this available for us to pillage 
That’s the Christmas spirit!
