I'm not saying I would spend $40 on this thing...oh who am I kidding? I'd totally drop $40 on this for my desk. Strike fear into the hearts of your enemies (or coworkers) with your very own Turret Desk Defender, powered by USB. When it detects movement, the wings open and it will announce the acquisition of a target, which is enough to send anyone running away from your desk at top speed. And yes, if you knock it over, it'll vibrate and be sad about its lot in life.
