made by Gustav Hellberg who is a Berlin-based artist. It reacts on changes in the rooms condition, which can be caused by people. The foundation of Hellbergs artistic practice lies in the public sphere, where he looks for an interaction between people, artwork and the public space. Thus it is constantly changing the bars scale, which also means that the visual information is constantly changing. The always changing art piece XYZ hangs in the air above the meeting square in Navet.
The blue light indicates humidity and the green light the levels of carbon dioxide in the air. The red light indicates temperature changes in the room. This also leads to an oscillating effect as it tries to adjust and balance its output. Each bar graph is connected to a sensor that controls the light sequence. The algorithm is constructed to alter the scale according to the fluctuation of the sensor values. They are all important entities that determine human existence. The white light indicates each diagrams electric power consumption. The processors that are controlling the sensor data and turning it into light sequences are programmed so that they will present the change in the values produced by the sensors.
