I've been looking for this the entire week now. Just switched from a PC to a rMBP. Sofar it's easier then I thought. But I want to make some changes to the look&feel of Mountain Lion. Is it possible to chnage the standard Apple Dock Icons into a set that resembles the iOS 6 or 7 icons? I see a lot of icons sets, but have not yet found one that could for example could replace my OSx Mail icon in the one that looks like the mail icon on my iPad and iPhone.
