“Of How We Have to Leave Doubts, Expectations and the Unachieved” is an installation by André Gonçalves. Each time a visitor enters the room, a balloon is released. Industrial fans then blow the balloon around in an unpredictable way. A camera sends an feed to a computer which calculates the distance, angle and speed of the balloon. This data is passed on to a paintball gun which then tries to shoot the balloon. It would have been nice if the visitors could control the fans so they could try to save the balloon from the gun. But the computer is probably faster than any human interaction.
