I mentioned this to Paul in an IM. He was unsure why the 'laggy' scrolling, or 'choppy' behavior was happening when the visitor scrolled up and down, in a quick fashion.

(Firefox 9.01) Win7, 4GB RAM, ATI Radeon GFX Card.

I suggest the background be 'fixed'. (The denim png file). I always fond fixed backgrounds are very perform-ant.

Maybe I'm wrong, but years of coding websites, you learn a thing or two. Call it intuition if you will.

I'm not an authority on this, but I remember a talk by Paul explaining the browser's paint / reflow mechanism.

I always got the sense, un-fixed backgrounds caused the reflow/paint to go crazy...

Also, what's the buzz with them circles in the BG? For a site claiming to use new browser features wisely, you over-embellish and confuse your users with over-engineered bulky choppy graphics?

Just a thought
