As an added bonus, it can automatically track a moving subject.

The 3-axis StabCam fits all models of GoPro Hero, provided they're kept in their housing. Because it works with GoPro mounts, that means it could be mounted on a helmet, suction-cupped to a car, stuck on the end of a pole, or ... you get the idea. It's also "weatherproof," so snow and rain shouldn't be a problem.

Power is provided by a removable (and thus swappable) battery that's reportedly good for approximately two hours of pitch, yaw and roll-compensating action.
