Mojigen & Sujigen (2016)



Our daily life is surrounded by so many static things, especially letters and numbers. These are two-dimensional symbols, and usually static images. But we originally cannot write a letter or number without moving our bodies and spending time. Thus, we can consider that each number or letter potentially has a time axis. In order to reveal this hidden time axis and express its secret movement, I created two complementary devices “Mojigen” and “Sujigen”.

Mojigen has eight control points, and draws a single line in the midair by expanding and contracting coil springs with robot arms. Its trajectory seems alphabet when viewed from the front. However, if the audience change the viewpoint, its time axis and the trace of movement will appear. Sujigen has ten axes of rotation, and is hanged from ceiling. It seems a bustle mobile at a glance. However, if the audience look it up, s/he will see numbers in spirals.

Mojigen and Sujigen are also called as "One-Stroke" in English and "一筆" in Chinese.
