I'm trying to emulate this effect: http://meyerweb.com/eric/css/edge/complexspiral/demo.html on my blog: http://segment6.blogspot.com/
It works, but with one problem: Firefox lags really badly scrolling the page. If I make the background attachment not "fixed", it no longer lags, but the effect doesn't work. Can this effect be achieved without fixed positioning or the lag somehow cured?
I've tried using background-position with percentages but it seems to position based on the width of the element, not the width of the page, so I can't line it up correctly for varying window sizes.
