It's built in Flash.

I was wondering how to build this kind of site without Flash and using Jquery.

I thought of a big container div without scrollbars and overflow hidden (so no scrollbars will be visible).

The content of this div should be x-scrollable by dragging the mouse.

The content of this div is each of the columns that load its content via ajax and expands right when ready... each column must be y-scrollable by dragging the mouse and must allow collapse/expand.

With this in mind, I don't really know where to start from... 

Which pluggins do you recommend ?

Do you know of any similar sites built with jQuery?

I have seen similar ideas in "timelines" like the Google history one with x-scroll ... but never with both x and y scroll working together.

Any help is appreciated!

Thanks
