What u'll need
-A good icon pack ( personally i prefer the Moonshine icon pack)
-Minimalistic wallpapers (Google Play App: Minimal Wallpapers)
-And some creativity of course :)
Step 1. Download and install the nova launcher app from play store
For simplicity , go to Nova settings>desktop>uncheck label icons option
Step 2.Download the icon pack
Install the icon pack and then go to Nova settings> look and feel> Icon theme> and select the icon pack you just downloaded
Step 3.Download and install the BobClockD3 widget
Drag the widget from the app drawer to the home screen and place it anywhere ( I prefer it placing it at the corners of Home screen)
