A desktop application on the web

[webflybullet]

I found a desktop application on the web as follows:



Demo: http://www.tomatocart.com/products/store-demo.html

I wonder how to build such application. It seems to be very complicated.

Is there anyone know the principal for such application?

Thanks in advance

if you view source on the page once you open the application you can see that it is just extremely clever use of html/css and JavaScript. That probably pull information from php through AJAX

difficulty: medium to high
amount of tedium: extreme
