Get the moto x gesture on your android simply
QuickCamera is a free and open source application that lets you quickly launch the camera app (normally or from the lock screen) with a simple gesture that involves twisting your wrist twice, quickly. It’s the same gesture that’s used to launch the camera app on the Moto X. Pull out your phone, perform the gesture and the camera app will be ready to take wonderful photos. No need to wake the phone or press any buttons.
