processor - controlled objects , such as inter - communicating processor - controlled blocks , present changeable individual characterizations to a user . the objects comprise a processor , a power source , a communications unit , a response generator and a proximity sensor adapted to sense the close proximity and relative position of similar objects . a user manipulating the objects can cause , over time , designated objects to inherit characterizations and properties from other interacting objects to permit scalability in a set of such objects . interactions further generate sensory responses in the response generator of a specific object or otherwise in a response generator associated with another similar object based on proximity , relative position and the individual characterization presented on and by those interacting objects at the time of interaction . a set of objects has vastly extended interactive capabilities since each object is capable of dynamically taking on different characterizations arising from a meaningful combination of properties from different conjoined objects .
