Snow Script

Recommended Posts

If your in the xmas spirit or it is snowing where you live like it is here in Ohio, then I found an easy to use snow script that uses no images and thought I would share..

<!--Simply copy and paste into <BODY>  
    Just above the </BODY> tag. -->

<script type="text/javascript">
/*
Snow Fall 1 - no images - Java Script
Visit http://rainbow.arch.scriptmania.com/scripts/
 for this script and many more
*/

// Set the number of snowflakes (more than 30 - 40 not recommended)
var snowmax=35

// Set the colors for the snow. Add as many colors as you like
var snowcolor=new Array("#aaaacc","#ddddff","#ccccdd","#f3f3f3","#f0ffff")

// Set the fonts, that create the snowflakes. Add as many fonts as you like
var snowtype=new Array("Times","Arial","Times","Verdana")

// Set the letter that creates your snowflake (recommended: * )
var snowletter="*"

// Set the speed of sinking (recommended values range from 0.3 to 2)
var sinkspeed=0.6

// Set the maximum-size of your snowflakes
var snowmaxsize=30

// Set the minimal-size of your snowflakes
var snowminsize=8

// Set the snowing-zone
// Set 1 for all-over-snowing, set 2 for left-side-snowing
// Set 3 for center-snowing, set 4 for right-side-snowing
var snowingzone=1
