bitplay is selling desk lamps that can be turned on and off with a gun-shaped remote controller. With one of these on my desk, I'd get nothing done all day.
User can fire the "gun" to turn the light off. The light goes out and the lampshade knocks to the side, showing that it's been hit. To turn it back on, simply shot it again, and the lampshade will raise up slowly and turn the light back on at the same time.
Great little video to accompany the product:
