“Nyoro-bara-pichapicha machines” is a site-specific work, which explores the idea of “temporal machines” formed between the environment and human hands. As the work has organic substances inside the circuit, it adopts the process of oxidation and corrosion inside the machine. Hereby, the work is put under the time-based change, which makes the machine fluid, unstable, and constantly heading to corruption. In addition, as some parts of the circuit begin to dissolve in water through time, the machine appears and disappears repetitively via the behaviour of the viewers. Further, the moisture of the work soaks into the wall and even the surrounding objects are taken into the inside of the machine. By exploring a temporal machine that corresponds with the environment and the artist, I further speculate the possibilities of alternative new-media representation.
