My thoughts on the iOS 7 icons...yuck.

The icons are a designer's nightmare. The gradients on stock apps go in different directions. I can't see how this got past Jony. 3rd party apps bevel when that doesn't fit the theme. The shadow are too light and too dispersed so it doesn't give any sense of floating icons. They should keep the size of the shadow around 15 instead of 50. At the end of the design phase, I think they should have put an Android phone next to it to see if they have a better design. At that moment they should have realized they should start over.
