Not a code update, but an optimized suggestion. As I know many of you will start using this on Christmas Eve.
Suggestion:
If you know your community has a lot of mobile web users, such as Apple iPod, setting the snow fall value count to 20 works best. (original value is 35).
PHP Code:
// Set the number of snowflakes (more than 30 - 40 not recommended)
var snowmax=20
Happy Holidays
