This works really well! Check the website in my sig for a quick demo. You can change the color of the snow too!

I love JQuery! Thanks Gunsmoke. The work others are doing to add libraries to it is incredible.
I'm currently deep onto a script based on fabric.js. This script is totally awesome. I'm using it to build a custom mapping solution for pest scouting. It's a lot like CC's menu builder where there's so many settings to customize that you can easily get overwhelmed if you don't pick one thing at a time to focus on.

I'll leave the coding to you! But I am starting to like jquery and all the things it can do. And it's really not hard (if I can do it, anybody ...) to integrate into a Coffeecup page.

There's lots of toots out there and some great forums for help when the the eyes start getting cloudy.

And the jquery snow effect is easy to add into a SCCP site too!!

Thanks for the link Gunsmoke!

Yea, I like these little tidbits too! What my family calls 'gee-whiz' stuff!
