Jquery to slide content but show previous and upcoming content

I have been working on this all weekend. I am trying to create a centered content slider that allows the previous and upcoming posts to be visible (not hidden in overflow)

I need for the image that is shown to be centered with the upcoming and previous images visible to the left and right.

imageflow doesn't quite cut it http://imageflow.finnrudolph.de/

this really illustrates the best what I am attempting to do: http://www.nickyandcookie.com

i basically need to show whatever is held in the scrolling container while keeping the active image centered.

Thanks for any help or direction!
