LAS VEGAS -- Sphero isn't your typical ball. Besides rolling at your iPad's command, the cool-yet-creepy device is enhanced with augmented-reality games.
Sphero launched at CES last year, and since then it's grown: Where there were once a few games there are now 21. The ball costs $129.99, but almost all of the games are free.
In a brief hands-on at CES 2013, we got a chance to check out the Sphero's new augmented-reality abilities. We were impressed that the zombie game quickly adapted to the floor of a busy showroom in a fairly realistic manner (when an unsuspecting attendee breezed through the frame, one of the zombie avatars disappeared behind him).
