Each week, we spotlight a cool innovation recommended by some of the industry's top tech writers. This week's pick is a digital license plate. License plates have remained "virtually unchanged vestiges from the dawn of the automobile," said Eric Taub at The New York Times. No longer. The California company Reviver Auto is swapping out "old-fashioned stamped plates for digital screens." The plates, which are connected to a cellular network, have a screen that "can display anything," including vanity plates or a warning if a car is stolen.
