How about an anti-theft alarm, maybe one that would flash red and white, and the volume would be set to the maximum. This would be triggered off of the accelerometer, like a motion sensor in a car, and programmed so that it couldn’t be shut down by the power button, volume button, home button or the mute switch. You would need to input a password to shut it down or it would auto reset after say 15 minutes. I think you guys are getting the idea here.
