This is an improved version from previous Code1k.com code, Script effect snow for blogger. This version of snow will fall and left in a period when falling to the bottom of the web page, without delay and without embedded link snowflake image file to avoid image links die. This version is more smooth effect snow will fall and feel simmer as true, on the other hand is no longer embedded image should not be afraid the links die and not depend on the coordinates of the mouse pointer.The code is very suitable to decorate website / Bloggercho Christmas.
