The idea for a sports game described in the Harry Potter novels and called Quidditch may soon come to life thanks to the efforts of the Japanese inventors from the University of Tokyo. A tiny device is a ball with a built-in drone that can be beaten like a normal sports equipment, but you can also control it from the outside, even force it to operate according to the program. Rekimoto’s invention imitates actions of the flying golden Snitch. It should be reminded that this ball is the main goal, which is released after the 17th minute. Its catch brings 150 points according to the book version and only 30 points in the real world game.
