The pixels of The Pool are made from the 1999 Limited Edition Christmas Furby™, modified to reveal only the eyes and mouth in a softened triangular shape. Each pixel is actuated by a motor to achieve two visible states, open (and talking) or closed (and silent). The pixels are augmented with a PIC16F873 microcontroller that prompts the Furby™ to speak in response to viewer proximity, as determined by an infrared detection system. Although the Furby™ pixels retain their original logic, the added microcontroller is programmed to control their behavior in an unorthodox manner. Furby™ normally has sensors that respond to physical interaction by a human or another Furby™, such as tummy tickling, back rubbing and infrared communication. Our modifications make the Furby™ "think" these inputs are occurring even though the inputs are fully simulated by custom software. In other words, Furby™ meets virtual reality and we have full control over a talking, animatronic pixel (software engineered by Steve Gray).

According to the lifespan waranty on a Furby™, the living artwork has a guaranteed lifespan of 3 months continuous operation. As the Furby™ pixels wear out over time, a static composition is left behind: the residual of user reflection.
