iOS 7 is not something that you will be able to get the gist of by seeing screenshots — you have to use it, experience it. While the operating system is unstable (since it’s still in beta), the interaction is pretty awesome.
Also, it is important to note: whomever designed this must have been influenced by Dr Noel Mayo. Furthermore, Lutron apps will look great on iOS 7.
