Kinetic art has a persistent failure mode: the mechanism becomes the subject. You look at the motion, admire the engineering, and leave having thought about the machine rather than anything else.
Yang Jung Uk avoids that, and the way he does it is worth studying. His sculptures — small motors and thread affixed to slender wooden rods — are built to carry what one description aptly calls the anatomical logic of tendons and ligaments. They don’t look like robots. They look like the inside of a body or the rigging of a puppet, and they move the way those things move: pulled, tensed, released.
People in Prayer is at P21 in Seoul from August 31 to October 9, 2026. Yang received the Korea Artist Prize in 2024.
Narrative machines
The subject of his work is people, usually ordinary and overlooked ones, and the mechanisms are there to stage their stories. Light and shadow, sound and motion cohere into what amounts to mechanical theatre: a moving armature throws a shadow, the shadow performs, the motor’s noise is part of the score.
That inversion — mechanism as narrator rather than spectacle — is the useful idea for anyone building kinetic or interactive work. The engineering is in service of a story about someone, and the materials reinforce it. Thread and thin wooden rods are domestic, cheap, fragile things. They read as human scale and human effort in a way aluminium extrusion and stepper motors never do, even when a stepper motor is doing the work.
Why it’s here
We cover a lot of work in which the technology is the content — models, sensors, code. Yang’s practice is a reminder of the alternative: technology as grammar, deployed so consistently that you stop noticing it and start watching the thing it describes.
There’s also a craft lesson. Thread-and-motor mechanisms are within reach of anyone with a workshop and a microcontroller. What makes these work isn’t unavailable technology but a decision about what the motion is for, made before the building started. That’s the part that’s actually hard, and the part no parts list will give you.
People in Prayer runs until October 9, so there are three weeks left. Anyone in Seoul this month should also note that the season is unusually strong for technology-adjacent work — Kim Heecheon’s Moles is at Seo-Seoul Museum of Art until November 8, and Christine Sun Kim’s Moon Mind is at Gallery Hyundai until October 18.
