Jquery Parallax Scrolling effect - Multi directional

I threw something together is jsfiddle for you.

http://jsfiddle.net/9R4hZ/40/

The script initializes the start positions of all of the objects first. Then handlers are set up for arrow key and mouse wheel. After that is the meat of the algorithm in the parallaxScroll function.

It uses the ARROWS or MOUSEWHEEL for scrolling.

There are from [left, right, top, bottom] transitions.

The HTML and CSS are really simple.

The JS/jQuery that runs it is self explanatory.

It's an interesting effect, that seems to be geared for artsy type sites.

Did you look into librairies like Scrollrama http://johnpolacek.github.com/scrollorama/ or Curtain http://curtain.victorcoulon.fr/?

I know in your question you mention that you already looked into different librairies but depending how they work it's difficult to really suggest how to use proper coordinates.

*edit1

If you didn't see it yet, the auther of scrollorama also did superscrollorama which give a bit more controler over the animation for example animation when an element is pinned.
