I hope this review is added here, because last time it wasn't...
This plugin doesn't work. After enabling the plugin my site didn't work anymore. I got a blank page with a fatal error (something about a "call to member and a non-object" on line 31).
I had to delete the files manually on the server to restore my site.

cute plugin.... nice decoration for your page for xmas... snowballs falling in your page....good one !
