Sparks fly as crazed inventor creates a very different kind of ‘electric’ piano

Inspired by those piano learning apps that show notes falling down the screen and sparking as they hit the keys, Mattias Krantz decided to take things one step further - well, several steps further - and try to create this visual phenomenon for real.
