An advantage of this method is that by not using scripts doesn't overload the blog, the disadvantage is that users with not so modern browsers, will not be able to see it (in Internet Explorer works for version 10 and up).
The snow will fall in the background of the blog, which, in addition, prevent interfering with links or content (because the flakes are images), also prevent blocking the visibility of the content of the blog.
You can see the demo in this test blog.
