Spinning ping pong balls around 2 axes. Intricate patterns turn into concentric circles. High speed, high precision stepper motors with custom drivers controlled by FPGAs solving 5th-order equations in realtime, with a focus on event timing. Also filmed with cameras to be presented on a series of monitors.
Two linked turn-tables, one playing vinyl cut to force the needle to hop, the other equipped with a pen mirroring these movements, drawing a seismogram.
