Since I am terrible with PaintShop/Gimp and all the image editing nonsense I had a buddy from work slap up a render of one. It looks great. I have the 3M Carbon Fiber Vinyl and as soon as I get the Evo I will put it together to make a beautiful device even nicer. It is not the flat CF it is the textured kind.
