Self Guiding Bullet

Now this is cool.

Designed with the military, law enforcement, and recreational shooters as potential customers, the bullet is four inches long and has an optical sensor embedded in its nose for the detection of a laser on its target, Sandia said in a release today. The bullet also has built-in guidance and control electronics that receive data from the optical sensor and then manipulate the electromagnetic actuators. And the actuators use that data to steer small fins in order to direct the bullet directly to its target.
