Scrolling Parallax is a new jQuery plugin that binds a parallax effect to the scrollbars and mouse wheel. This allows a background image or anything else to scroll at a different pace than the web page when a user scrolls around. The parallax effect that results is an easy way to create an illusion of depth on your website.
The Scrolling Parallax plugin is also very versatile. There are a wide variety of options including scrolling faster, slower, looping and reversing the animation and tiling the background to name a few. Addtionally you can attach the parallax to any piece of markup, as well as pass an image path as described above.
