How was jQuery and Javascript used on this site?
I'm pretty new to Javascript, but I've used jQuery plugins and slightly modified them before. I'm trying to make a bigger jump into gaining a more complex knowledge of Javascript, and to help me do this, I'm trying to recreate the javascript of this site: http://www.uniqlo.com/jp/supercoolbiz/

I'm wondering how they did a couple things: 
1) How do they get it to display a loading... (1%...100%) until the page is fully loaded? That is, how do they get the rest of the site to pop up upon loading, and how do you signal this as an event in javascript?
2) How do they get the divs to wiggle around on hover?
3) How do they get the images to change on hover so fluidly? (When you scroll over a single model, they rotate)

[Also, which parts use jQuery?]

I realize their Javascript is mostly found under view source. I'm just having trouble identifying which elements correspond to which script. If someone could just briefly walk me through how to do these things, I would greatly appreciate it.

Thanks.
