@Gargron This is the nicest snow-script I have seen yet. Not feeling super festive otherwise, I have decided to put it on the blog my fiancée and I run (sadly all private): https://diedritte.derdritte.net/

I made the snow a bit gray-ish because the page-background is white and fiddled with other numbers a bit. I am not a JS-dev, but that is some very clean code!
