Ball 2 is a sensor-equipped foam ball paired with an app that lets kids design their own games through conversation. The physical ball contains a custom circuit board and motion sensors, requiring no charging for over 500 hours of play. Kids speak their game ideas aloud, and AI processes their requirements to generate playable games instantly.
