14 awesome toys for the holiday wish list

The Mini is the latest tech toy from Sphero, the startup that turned Star Wars' BB-8 droid character into a robotic ball. Now, you can control the movements of its latest robotic ball with facial expressions.

At about the size of a standard ping pong ball, it features technology that tracks smiles, frowns and head tilts. The expressions correspond with a directional movement. For example, a smile will move the Mini closer and a tilt of the head moves it left or right.
