Chizuko Ninomiya is a contemporary art writer and a financial SE at the same time. She feels that her financial background gives an important feature when creating her work. With the prevalence of mobile devices, people have increasingly seen images and other data provided by system processing results, but most of the people are not conscious of the processes and programs running behind. She tries to present the programing language into artworks that are not visible in reality. She challenges to "light the invisible" by reconstructing it as a painting. Most recently, she has been creating a series quoting laws and judicial precedents to express her thought of controlling powerful information technology with human ethics.
