Jenny looks at the orderly line of vibrating Styrofoam balls hovering just out of reach. She can see Jones from the corner of her eye, fervently adjusting parameters on his keyboard. The balls respond by changing formation, a bit like those acrobatic airplanes, only there are at least twenty, sometimes more balls flying in perfect synchronicity. Occasionally a number of balls would drop out of formation for no apparent reason, only for more balls to arise from the table, resulting in a different pattern to materialize as if out of nothing. These pattern changes could be subtle, almost indiscernible from the previous, or dramatically different. Jones keeps telling her something about sound waves, standing still in some locust or was that low keys but anyway there the balls all fall down and Jones is looking at her with a grin that says "was I a good dog ?"
