Safari Ad Blocker

Ok, I saw this here once. It was a .css file, that when added to safari through some preference it blocked all those page embeded ads. What was it? I know of Pith Helmet, but I don't feel like installing something, I just want that file!

I found one. It looks like it just blocks the banners and flashwave ads, which is fine. If anyone has a better one, speak up! Here's the file, go to suprnova.org to test it out. You install it by downloading it and selecting it as the style sheet from the safari advanced preferences.
