This stack has the sole-purpose of creating a falling snow effect. Unlike other stacks of a similar description, Blizzard includes some extra features; like the ability for website users to turn off the effect (if they find it too annoying), and checkboxes to control which months of the year you want it to snow. Lots of other settings are provided to customise too; like the size of snowflakes, their colour, and their intensity. Setup is easy, with compatibility extended to cover most themes.
