Hey if anyone wants to see how to do this, here's an example I threw together with stuff from the internet. I'm trying to get some sort of active desktop on my vista machine here at work, but at home, I've got a snowy desktop :P
Just unzip the files to a folder and open snow.html. To edit the java, just open up snow.
js with notepad.
This is the number of flakes on the screen at any given time.
var SNOW_no = 250;
for the same amount of flakes as ppcgeeks, use like 15-25. I use 250 to make it look ridiculous.
