If you're like me, you're thinking the vibrating cellphone in your pocket will actually alert you to an incoming call, which it often doesn't because of its anemic lack of vigor. This goofy egg-shaped Mobile Phone Sensor Clock has an antenna growing out of its head that can detect incoming cellphone ring signals, which makes it kick its little legs like a chipmunk scratching itself. That I'll notice.
Just make sure your cellphone isn't more than 6 feet away from the little bugger, and it'll get the heebie-jeebies every time a call comes in. Hey, it also doubles as a clock. Sign me up. It's $18.94
