wow - this opens the gates to some cool experiments with some funky transparent pngs... scrolling down a page was never that cool.

I can see the possibilities, like things racing past each other. The sample though, I would sooner think the browser was having trouble rendering the backgrounds and it was just plain glitchy, not that it was some effect anybody went to any trouble for. Have you noticed this on pages when certain background elements don't scroll with the page, justs looks buggy. Again, something could come of this, don't mean to sound too negative. Could negative values be used to make the backgrounds go in reverse even? It would be great for a racing site.
ty,
change the appropriate bits in the original code into these:
var groundparallax = calcParallax(53, -10, posY);
var cloudsparallax = calcParallax(400, -.5, posY);
and it will do what you asked for.
now, more interestingly for me, i am going to modify this to make it work horizontally.
Hey schnuck, good catch on this one, the possibilities are just amazing. It might just call for some creativity/imagination and a stimulus known as caffiene, lol.
Small patterns with this technique are somewhat overwhelming, but with the right BG's, it would kick butt.
None of my browsers on any of my PCs managed a smooth scroll on that one, sadly. :/
I've personally been waiting for this for years now. Good to see others do something about it too.
