depth effect using Javascript (jQuery)
<p>Does anyone know (as in <a href="http://james.padolsey.com/" rel="nofollow">http://james.padolsey.com/</a>) how the upper body layer is scrolling at a faster speed while the background is scrolled at a slower speed making it give an effect of depth??</p>

<p>Can I implement multiple layers (more then 2) scrolling at different speeds using the similar concept??</p>
