Falling rain...HTML Code help, Coding help Options

[link200345]

Hi. I just found this code sumwher and I was just wondering if sum1 could mess around with it so instead of the rain swaying as it does now, make it so it will fall straight down on the page [check out my xanga site, xXMassMurderersXx, to see what i mean] and maybe make it a little bit faster...thanks. Heres my current code....
