The concept rethinks the iPod (music) control. This is
accessible via the apps Switcher by a wipe to the left. Instead of simply displaying the music app icon, a rotation lock, and three control buttons (song before, song back and pause button), demonstrates the concept, the music control buttons at the bottom of the screen, while a controller is placed directly over it. Sound information and album artwork are still on this control knobs and buttons.

I can see an implementation of the concept come as Cydia App on us. Of course we miss it even an iPhone 5 jailbreak. This is currently developing aer pod2g already. It will be still a matter of weeks / months before we will see results.
