If you're running Android 1.6 and above right now (which should be most of you), you can now download the latest update to Gesture Search from Google Labs. For those not familiar with the app, Google has created an app that allows you to search everything on your Android device by simply drawing out symbols or letters on your device's screen. 

The new update brings the abilty to literally face the phone away from you and doing a "double flip," resulting in the app starting up to begin your search. This is a step forward, as the app once required you to exit to the home screen and select the widget to run the app.
