Moving Boxes - Fluid width + Supersized

I’m trying to incorporate Moving Boxes with Supersized. I want to acheive two things.

  1. Is there any way to make Moving boxes 100% width, which fit all the browser window. ie, prev and next images float to both sides of the window instead of fixed width and current slider is still in the middle.

Below is the sample screen.

  1. How do I link Supersized images with Moving Boxes. ie, background image should move together with slider when you click arrows or prev/next images.

Below is a sample demo

Any help?
