Necro'ing this thread because it's that time of year again.

A simple, lightweight and versatile implementation for all of us getting ready to build a winter theme.

Thank you for this.

I used the snowstorm js script, edited it down some to try to make it faster on slower devices. I then added a Show snow checkbox in preferences. Finally, I placed the script in a rotating ad and set it only show for those who have checked the box. The rotating ads addon is really good for presenting things to target audiences using the fields they have set (and custom fields you have set). I use it mainly to show holiday banners to only the countries that celebrate the holiday.
