Lamp Works Without Touching, Clapping
The Airswitch Lamp works without ever having to touch it. You just swipe your hand over it and it turns on and off. You place your hand over the lamp and either raise or lower it in order to adjust brightness. They cost $79 and come in red, orange, blue and green. The only problem is, unlike the clapper, you have to be within arm's reach of the lamp in order to control it. I have a better system, but it works on a similar premise. I swipe my hand across my girlfriend's ass, follow it with a "get the damn light woman" and ta-da, off it goes.
