Return to SpringBoard - Page Curl

It would be nice to have the luxury to return to the SpringBoard from anywhere without using the Home Button. But, what's the best way to initiate that action in an native/intuitive way?

Here's how I propose this could be done. If you drag from off screen on the bottom corner of your device (left side or right - doesn't matter), the page starts curling If you continue curling (dragging your finger), it will peel the page off and you'll be right back at your SpringBoard.

Fun huh?

Although barely visible, I'd like to give a shout-out to Robert Padbury for the Diamond Grid Wallpaper and Louie Mantia for the S.H.I.E.L.D. wallpaper, which was used as the background behind the initial device image.
