iOS 7 icon Grid

I know I'm not the first one who suggest this solution, but I was practising with some icon grids and this came out.

The iOS 7 icon grid actually uses Fibonacci's ratio, but the way it does makes the circle and outer icon shapes struggle. Applying the ratio to the icon shape -and not to the outer square of the file- makes the inner circle smaller and keeps it away from the icon borders.

The third step is a personal solution, just to create more negative space around the circle shape.
