Updated to iOS7 today and noticed the icon layout changed enough to need to make a new blueprint wallpaper. I don't have an iPhone 5 or 5c, or 5s but will make one for that when I get the screen shots.
More colors and variations to come.
Please leave feedback.
I am not sure if people hate the face that I put my mark on this or not, it is only visible when looking at the contents of a folder, so hopefully very minimal.
Note: this image was made at twice the resolution of the iPhone to better align the grid.
