INvention for today 11/11/08

I'm thinking of a little generator that would store up energy as the animal walked around. For example for a dog, when he got home you could plug him in and a little light would come on that would light up the area he travels. If he got up to pee on the corner of your couch in the night you would be able to hit him with a shoe because of the little light he had tied to his head. Cool idea, huh? I call it the dog catcher light. dc
