<script type="text/javascript">
// <![CDATA[
var speed=33; // lower number for faster
var flakes=100; // number of flakes
var colour="#ffffff"; // colour of flakes
var slush=20; // set to '0' for no slush or otherwise set to height at which slush melts
var over_or_under="over"; // set to "over" for snow to always be on top, or "under" to allow it to float behind other objects
