I just found about a new (temporary) feature for WordPress.com blogs. As it says here you do this to make it snow:
To make it snow on your site:
1. Go to your site’s dashboard.
2. Navigate to Appearance -> Extras.
3. Check the box next to “Show falling snow on this blog.”
4. Click the Update Extras button.
Since it is getting so cold here in Oklahoma City, I think this is a fun way to acknowledge it.
Cool!
