Inspired by the idea of Techno-Taoism advanced by Michael R. Heim, I realize that human as natural biology will inevitably fall into the abuse of digital technology. In this series called “endings”, I try to describe an intentional balance between the natural and the artificial to face the mentioned problem by the software Processing. “endings” is a series of abstract digital works of art which are based on trees and the form is inspired by “mandala” – the common symbol in India art and books about philosophy and religion.
