Ahh, adding snow effects to your websites with JS, the reason Javascript was actually invented in the first place, along with showing current time alongside your cursor ;).
PS. The JS is used just to generate and embed the code, snow effect is 100% CSS :)
Works on Firefox too. I tried adding <blink> but (thankfully) that didn't work.
Blinking Marquees were a big thing.
To make it even more irritatingly attention grabbing while trying to read something else, layer the blink (or fade if being slightly more subtle) so it occasionally blinks brighter. Use the "Cicada Principle" to make the blink unpredictable with minimal effort.
Strange coincidence, I was thinking about fixing that today...
