Created by Yuichiro Katsumoto, Mojigen and Sujigen is a collection of servo motors, connected together to write a letter by the means of manipulating the axis of the motor.
"A number or letter is a two-dimensional symbol. Also, it is a static image. But we cannot write a letter without moving our bodies and spending time. Thus, we can consider that each number or letter potentially has a time axis." – Yuichiro Katsumoto
