I've recently started playing around with some light customisation...
The wallpaper I found here
I'm then using Apex launcher + the "minimal" theme by 2D Art with a clean widget for the main screen with little else asides from search and settings widgets:
To access common apps, I've then installed the Pie Control which appears when I touch the edge of the screen:
Still some playing to do, I'd like to find/make matching camera/chrome beta icons for the bottom in particular, and making the pie colourscheme fit more.
The clock/weather/battery widget is a UCCW widget called "MotoBean Clock" by D Saif in the Play store.
