"Magic Eye" tubes are a type of tube common in older radio sets. Consisting of a fluorescent "target" area and a simple deflector electrode, these tube were used as tuning and VU indicators. As they literally operate at the speed of electricity through a wire, they still have application where a device that can indicate instantaneous changes is needed.
