And today’s award for ‘Display Technology That Will Most Certainly Never Catch On’ goes to Mitchell F. Chan’s The Ingenious Gentleman Don Quixote of La Mancha art piece which uses rings of water vapor as pixels to spell out Miguel de Cervantes Savaedra’s book of the same name. The rings are generated by an array of ultrasonic transducers in a bucket of water controlled by an Arduino. The sounds they produce are out of the range of human hearing, but produce tiny airborne water droplets which are then propelled upwards using another set of speakers producing subsonic sounds instead.
The video below shows the whole thing in action, but be warned, it’s not terribly exciting. Since it can only produce a single letter at a time, Mitchell says it will take approximately an entire year to spell out the entire book.
