Ready to get in Christmas mood? Want some snow into your SharePoint site? 
With thanks to Todd Bleeker:
I am still refining my enhanced Search Web Part and my Subwebs on the Quick Launch Web Part (sorry for the delay, I hope to finish these over Christmas break). You're going to love them.
However, I thought it would be fun to release a simple, holiday CEWP. We are using this Web Part on our own portal and our staff has gotten a kick out of it. So, let it snow, let it snow, let it snow (see figure 1).

Just save the snow.dwp locally, import it onto a Web Part page, and ideally change the location of the snowflake image. Of course, you can use any snowflake image that you like. Simply edit the JavaScript source directly.
