Now I know you can make your dock look like coverflow by theming in winterboard, but this can be a long and arduous process especially for those who don't have Photoshop or the scripts or know how to make the icons.

My idea is a dock modification that would, when an icon is dragged into the dock, convert it into coverflow style based on where it is placed. Depending on the position of the app it's icon would change. You would then be able to scroll through the dock with each icon inverting and changing based on it's position, much like iTunes' coverflow.
