Louie Mantia is a former Apple icon designer, so he actually has even more right to do that thing every designer now does. You know – redesigning iOS 7 icons. And since he has worked on some of the original pre-iOS 7 icons too, he has both the skills and the knowledge on how good icon design works. The fact is that it actually does look much cleaner and nicer, but also a little confusing, because if icons all shared that very consistent style they’d be harder to process by our eyes. So there are compromises everywhere I guess. But still worth a shot, I especially like the safari icon.
