List with descreasing opacity while scrolling

Hi everyone,

I am trying to make a list with static label items(home menu) where the opacity of a given label decreases as i scroll away from it. The effect would be exactly the same as in Hitchers FTV skin. Now i could solve this by adding a layer of the background image on top of the menu, and diffusing it with a semi-transparent image, and then add some slide animations to make it appear as if the labels are gradually decreasing in opacity as i move away from them(this is how the FTV skins does it). The problems is that my background is not a single color, and therefore i cant do it this way.

Do any of you have any idea how i could solve this? The only way i can think of is by making a grouplist where i define each menu item with fade animations for every focus position in the grouplist, which seems a bit overkill Big Grin

Thanks in advance.
