On voidness, performing John Cage's 4'33''
How can we efficiently perceive an existence?
- By voidness. That is, a perception of existence via non-existence.
This 4’49’’ video is made of two parts: A silent, void part that is actually playing John Cage’s notoriously famous 4’43’’, and 16 seconds of perceptible intermission which is placed between. Here, the sudden presence of audiovisual stimulus within intermission, which is followed by complete silence for more than four minutes, induces spectators to finally acknowledge the existence of the artwork and its concept, which would have been otherwise unacknowledgeable.
Then why should the intermission be exactly 16 seconds? Our Narrative Fallacy induces us to give false justification to the 4’33’’. This artwork criticises and humiliates such a tendency, by using its very strategy of giving a false narrative to 4’33’’ explicitly, which in this case is the following mathematical equation.
4’33’’=273s=13*21s=(17-4)*(17+4)s=17^2s-4^2s=4’49’’-16s=(Whole Length)-(Intermission)
This equation is logically flawless, creating a perfect justification for the 4’33’’ on why its length should be exactly 4’33’’. Hence, its mathematical perfectness does not imply that such a narrative of interpreting the running time should be also correct. Thus, this artwork metaphorically criticises contemporary society which is obsessed with data and numbers, which look logical and faultless, but which in fact only create an illusion to cogitate our incognito.

Jeanyoon Choi
Jeanyoon Choi (b. 1999) is a Korean computational artist and researcher. He designs and researches multi-device web artworks that reflect the complexity of contemporary socio-technological systems, including AI, algorithmic culture, and economic structures. By interconnecting mobile devices and screens, these artworks create provocatively interactive environments. To develop their conceptual foundations, he draws on art, philosophy, and his scientific background, then uses software engineering and design to translate these ideas into interactive experiences.
He holds a BS in Industrial Engineering from Seoul National University and an MA in Information Experience Design from the Royal College of Art, and is currently a PhD candidate at KAIST's Experience Design Lab (XD Lab). He has also taught Computational Design Practices in the Interaction Design Department at K-Arts (Korea National University of Arts). His work has been exhibited internationally at Ars Electronica, Istanbul Digital Arts Festival, IKLECTIK London, Centre Culturel Coréen, and KAIST Art Museum. His papers have been published in the proceedings of ACM DIS and in the Leonardo journal (MIT Press), and he has served as an academic reviewer for ACM TEI, NeurIPS Creative AI, and Digital Creativity.
