Sorry not programming this time, but this is a great little toy. An App-control robot from Sphero based on the Star Wars new Sphero BB-8 Droid . The video shows it in patrol mode, which in the case of my one is either rolling under the chair or rolling around the room.
One of the other parts of the app include an augmented reality option where on the tablet it appears to be projecting messages and videos (included ones you create).
It is difficult to resist playing with this one.
