How it works:
The embedded screen shows a sequence of laser strings, that need to be “played”, in order to get a melody. Correctly played melody gives access to another, more complicated one. Crossing a wrong laser beam erases the score and redirects to the beginning of the game. A free mode is also available, where one can play the harp like a real instrument.
Where does the sound come from:
The laser harp is equipped with set of laser light emitters, and correlated light sensors. “Playing” a string means crossing a laser beam, and activating a sensor. The sensor then sends a signal to the computer, which generates sound in real time, giving the illusion of actually playing the laser strings.
How it’s made:
The harp is situated on a plinth, 500 mm height, made from lacquered MDF. Harp itself is also cut from MDF. The shape of the plinth gives unobstructed access to the exhibit.
