Had a thought for an object. My thought was an item that uses human bodies to calculate something. Thinking that it function in one of two ways. One, it will activate in response to being asked a question, and will use them to calculate the answer, the number of affected individuals in its range corresponding to the difficulty of the question. Or two, it is functioning independantly and continuously takes in any humans that enter its range, adapting the movements to accomodate. For this one, its range may or may not expand over time/as it gains additional people.
Not sure what others might think of this idea, but here it is. Any thoughts?
