In 2005 I wrote about Printball by the talented Benjamin Gaulon, a sort of ink jet printer using a computer controlled paint ball gun. In 2008 Nvidia/Mythbusters (may have been) inspired by this and produced the same piece, but also a super charged Mona Lisa version.
André Gonçalves last year created the installation Of How We Have to Leave Doubts, Expectations and the Unachieved.
From the website…
“Motion detection sensors track the presence of visitors in the space, after this detection the fans inside the balloon aquarium start to spin, making the balloons inside it float, a smaller directional fan by the opening of the aquarium is running at full speed in order to push one balloon out, after a few seconds the fans started spinning the aquarium door opens through a pulley system controlled by a servo motor. An infrared proximity sensor, located right outside the door, tracks when the balloon exits the aquarium and triggers the pulley system to close it’s door as well as triggers the fans outside the aquarium to spin at their full power.
Due to the wind generated by all the industrial fans on the floor the balloon is forced to float beside the wall and enter the camera field of vision”.
“As soon as this happens the computer, receiving the image from the camera analizes the incoming data and calculates the distance, angle and speed of the ballon, then based on the gun current position calculates the best spot for intersecting the ballon, after this calculation the computer sends the intersection position to the motors that control the gun aiming position and shoots. if the it fails it will shoot again until the balloon is blown away or this manage to leave the camera’s field of vision”.
