Cadence of the Spiral explores time as something elastic, relational, and alive. A strip of stainless spring steel is shaped into an ever evolving form by thirty mechanical arms moving in subtle, phase shifted rhythms. As the spiral breathes, twists, and reorganizes itself, no two moments are ever the same. Inspired by the mainspring of a mechanical watch, the work reinterprets coiled metal as a vessel of stored energy and temporal flow. Rather than repeating motion, it reveals change through controlled variation, time is not measured but felt.
Press Kit
- Unique Properties
- A long stainless-steel spiral is dynamically deformed by independently actuated arms, generating continuous reorganization through tension and release. Unlike static sculpture, the form never settles; it is constantly restructured into shifting orders. The spiral functions as a physical model of time—elastic, unstable, and relational. Controlled irregularity replaces mechanical uniformity, allowing viewers to perceive time not as measurement, but as a living and evolving order.

- Production Technology
- A custom-fabricated stainless-steel spiral plate forms the core structure, paired with a bespoke linear actuation system developed for this work. Most mechanical components—including joints, mounts, and structural interfaces—were custom-designed to enable precise distributed deformation. Motion is coordinated through a PC-based control architecture enabling synchronized, phase-shifted oscillations. Parametric modeling and simulation optimized stress distribution and torsional balance.
- Design Challenge
- The primary challenge was balancing structural stability with expressive flexibility. The spiral required sufficient rigidity to maintain form, yet enough elasticity to allow dynamic deformation. Managing distributed mechanical stress while achieving organic motion demanded extensive iteration. Technological constraints of synchronized actuation and material fatigue also required innovative solutions to preserve both safety and poetic integrity.
- Project Duration
- The project began in Tokyo in March 2025 and was completed in November 2025. Prototyping and structural validation were conducted in Tokyo. Developed in collaboration with Seiko Watch Corporation to explore the cultural and mechanical heritage of horology, the work was exhibited in Japan and is currently being prepared for international presentation.
- Operation Flow
- The spiral slowly shifts between tension and release. As the supporting arms extend and retract, the form breathes, twists, and reorganizes itself. There is no fixed choreography; instead, subtle variations create moments of alignment and misalignment. Viewers experience a continuous transformation—sometimes synchronized, sometimes slightly off—evoking the sensation of time that never fully repeats yet always returns.
- Research
- This practice-based design research explores time as a spatial and kinetic phenomenon. Through iterative prototyping combining mechanical engineering and artistic experimentation, parametric modeling, structural simulation, and motion analysis were employed. Audience observation during exhibitions informed the study. The research identified perceptual shifts generated by micro-irregular motion, demonstrating how controlled instability enhances emotional engagement and contributes to contemporary kinetic art and experiential design.
- Inspiration
- Inspired by the mainspring of a mechanical watch, Cadence of the Spiral reconsiders the spiral beyond its functional role. The tightly wound strip of metal appeared as a vessel containing latent energy and rhythm of time itself. When gently lifted, it responded with subtle motion, as if about to begin a heartbeat. The spiral thus emerged not as an object, but as a physical manifestation of invisible time—an embodiment of tension and release within temporal experience.
