Motion-Powered Humidifier Promotes Enslaving Innocent Cats

The Wool Ball concept is as clever as it is devious. It's basically a motion-powered, ball-shaped humidifier that your cat is supposed to move. Of course, there's always a back-up battery in case the feline catches on to the scheme.

Then again, even if your cat did realize that you were secretly abusing it for better air, how could it resist playing with that ball anyway? [Coroflot via Inhabitat via Engadget]
