The authors take the reader on a journey through their process from conception to final design and implementation. Their narrative and use of sketches makes the paper easy to follow and accessible by any reader with minimal background in the field. What is most commendable in this work is their experimental implementation. It required 48 synchronized high-resolution displays. The author’s solution? Forty-eight smartphones. It is a practical solution and perhaps reminds us that we can research and contribute even if we do not have well-equipped laboratories with million-dollar equipment.
Florida was recently hit by Hurricane Irma. In preparation for the hurricane one of my coworkers purchased a generator so that in the event of a power outage he could keep the pumps in his aquarium running and keep the fish alive. He did use the generator. If he would have had a crystal ball that could display fish, not only would he be a proud owner of the most exotic digital fish on the planet, but he could have used his generator to power his refrigerator and lights instead.
