'Voice of Nature' that collects 'what the tree is experiencing' in real time and visualizes it as an annual ring

Trees have been staying in one place for many years, keeping traces of past climate change, forest fires etc in the annual rings. Thijs Biersteker , an artist based in Amsterdam in the Netherlands, has created digital art that monitors and produces such trees.

The annual rings appearing in the cross section of a tree are increased one by one every year, and by seeing the degree of growth, you can learn about various events such as climate change and wildfire that trees experienced in the past "Wooden record keeper It can also be said that existence. It is difficult for humans to feel climate change with a long span, but looking at annual rings makes it easier to see climate change on an annual scale.

Furthermore, Biersteker conceived, "What will happen if trees inform real-time about climate change?" Mr. Biersteker decided to install installation digital art in the city of China, Chengdu , which has a population of 14 million people.

Blanchard who picked out one tree standing on the site installed a large amount of sensors on the roots, leaves, branches, etc. and collected data from the tree from a total of 1,600 data points. Data reflecting ambient environmental conditions such as CO2 concentration and temperature, soil humidity and hit light intensity are output as ring-shaped digital data through a special algorithm.

This is how the art created by Mr. Biersteker is actually exhibited.

A distorted white line is displayed on the display behind the tree.

From a distance, the line of light extending from the ground leads to a circular display spreading over the background of the tree. The white lines spread from the center of the tree to the outside concentrically, ......

Sometimes the pattern displayed on the display changes.

Biersteker installed 12 sensors on a tree and gathered data from 1600 data points.

We also acquired data from the environment other than the tree itself, such as soil.

Passing data through algorithms ......

It is output as annual ring digital data.

This attempt to acquire real-time data from trees and reflect it on digital circles is something that can be said to be a "real-time annulus".

It appeals to people about climate change.

The digital annual ring spreads from the center to the surroundings while distorting ... ...

It responds to the light that the car passes through nearby roads and changes shape.

Sometimes a psychedelic color appears to float.

The more digital circles spread cleanly concentrically, the more it means that the tree grows healthy and growing.

However, as art, Biersteker says that it is ironic that the yen looks more beautiful than it looks distorted.

Looking at the state where many distorted circles overlap and distorted, it is somewhat fantastic.

A digital ring that emerges with changing color and appearance reminds people of environmental considerations.

Each ring position and waveform has its own meaning, and it tells us the situation of trees and the surrounding environment in real time.

This art entitled "VOICE OF NATURE" was done in collaboration with Delft University of Technology and it means that we gathered data without damaging trees.
