I was doing a little searching for creating CS3-like icons for other applications, when I came across this article at Creative Pro that shows how the CS icons redesign and their subsequent CS2 revisions were made. The CS3 icons are completely minimalist, moving away from the naturalist theme. Some people hate them and others love them. I think my stance is somewhere in between. I really enjoy the clean look, but I also see how confusion can arise from having so many square icons in the dock.
