Advanced animations with Javascript

I'm trying to convert a site from fl开发者_StackOverflow中文版ash to HTML/CSS/JS ( don't ask why, I just have to ) but I'm stuck about the animations that I need.

Please follow the link and look at the site: http://www.sultanahmetkoftesi.com

As you can see, the moving layers are accelerated when you move the mouse. That is exactly what I want to do.

I'd be glad if you can provide an example or snippet.

Pure Javascript or jQuery code is fine for me.

Maybe these two projects can somehow help you... 1. http://css-tricks.com/1660-jquery-robot/ 2. http://webdev.stephband.info/parallax.html

Good luck...
