Gothenburg Energy opened up a furnished container where visitor could vote on different projects they wished that Gothenburg Energy should focus on in the future. The voting was done by putting ping pong balls in one of four plastic tubes. By connecting each tube to the internet the current voting result could be showed live on a screen in the container and on the web.
Several prototypes were MacGyvered togethered to get the ball to bounce in a correct manner. From simple paper ones to wooden constructions. The final version was 3D printed and mounted in a plexi glass tube.
