title: Is this scroll effect custom or is this a well known special effect?
body: <p>I stumbled across <a href="http://bericotechnologies.com/" rel="nofollow">this website</a> and while it is too cluttered for my tastes, I love the depth effect that you see as you scroll. There appears to be a layer that is masked and scrolls at a much slower speed than the main layer. I was just curious if this special effect is something canned that can be slapped into a website or not. It would be interesting to try and reproduce it from scratch. I have a hard time distilling where in the code this effect is being carried out when I view the page source.</p>
