So I was wondering if anyone skinned the program Portable Apps. While it has it's limitations skinning wise, it is still a relatively easy to skin app, with only three things needed to be skinned: The background (jpg), the header (bmp for transparency), and the "drive space slider" bar (bmp). Here are some images to show what I mean:

My Darkstar Version:

My Invader Version:

and My XenoMorph Version:

Hope you all like them! 
And no, before anyone asks, I do not have permission from Stardock/Alienware for these, so I can't send the theme to you.
