We asked you to rethink what displays can look like and you didn’t disappoint. From almost 150 entries the judges have winnowed the list down to ten projects which are awarded a $500 prize and will go on to the final round of the 2021 Hackaday Prize in October
In a world where there’s an HD (or better) display in every pocket, it is the oddball ideas that tend to turn heads. High on that list is a volumentric display that levitates a tiny foam ball on ultrasonic transducers to draw 3D color patterns before your eyes, or the volumetric display shown above that works with a sheet of film and motors. Or how about a take on a laser projected display that uses a phosphorescent screen so that the path of the laser persists, fading in time for the next infrequent update.
