Okay, now for me!
This is my Windows 8.1.1 Pro PC in disguise to look like Windows 7...

I blocked some things out, so some stuff are missing like my PC name and Product code
Then, this is my Nexus 7 2nd Gen:

Lock Screen Home Screen Drop Down Bar Screen
Also, I used Paint.net again to block some of the stuff out for privacy
I used a backround from iOS 8 because it looks beautiful, you know
I don't use Cyagon Mod for my Android devices though
But my tablet is running Android 5.1.1.
