Innovative Seaweed-Based Lighting Installation: Slow2 by Su Yang Choi













Designer Su Yang Choi's latest creation, "Slow2," represents a significant advancement in material and spatial design, building upon the foundations of her Slow Project series. Unveiled at the prestigious Salone Satellite 2026 in Milan, this captivating lighting installation draws inspiration from "baramgil," a traditional Korean architectural concept that ingeniously uses aligned doors and windows to generate overlapping visual pathways and natural airflow. The installation masterfully translates this ancient wisdom into a contemporary context, showcasing an innovative approach to spatial perception.
Occupying an exhibition space of 388 × 200 × 288 cm, the "Slow2" installation, measuring approximately 150 × 55 × 160 cm, employs visual layering to enhance the depth of the space beyond its actual physical boundaries. It comprises two circularly structured elements that interlock vertically and are arranged in repetitive sequences. Rather than relying on physical expansion, the design creates spatial depth through a harmonious interplay of transparency, repetition, and the seamless continuity of visual lines. The project integrates a unique biodegradable material, meticulously developed by Choi from seaweed-derived agar, completely free of synthetic chemical additives. This material is not merely a substitute for conventional industrial materials but an expression of an independent material language, possessing distinct formal and aesthetic qualities. Complementing the seaweed-based components, the installation also features LED lighting, a steel armature, insulating tubing, adhesive, and natural pigments, demonstrating a thoughtful blend of sustainable components with industrial fabrication techniques while ensuring a cohesive structural performance and visual appeal.
The formal arrangement of "Slow2" echoes the profound spatial principles found in traditional Korean hanok architecture, particularly the "baramgil" concept. This concept emphasizes aligned openings to create multi-layered perspectives, ensuring a continuous visual connection between successive spaces. Choi's installation transforms this principle into a linear composition of repeated circular elements, each approximately 50 centimeters in diameter and positioned at 30-centimeter intervals across 4.5 stacked layers. This meticulous arrangement allows for an intricate dance of light, shadow, and visibility to permeate the open structure. The construction technique pays homage to the stacking methodology of the Ten-story Stone Pagoda of Gyeongcheonsa Temple from the Goryeo period, with layers of the seaweed-based material intricately wrapped around a central metal framework. This process creates stratified linear textures reminiscent of the stone tiers in pagoda architecture. Color, derived from natural edible pigments like paprika and gardenia, transitions subtly from the material’s inherent tone at the base to deeper red hues towards the upper sections, reinforcing the organic connection between the material's composition, structural form, and the installation's biodegradable ethos. As part of the ongoing Slow Project series, "Slow2" thoughtfully examines the multifaceted potential of biodegradable materials to function as structural elements, visual systems, and spatial mediums within modern design practices, pushing the boundaries of sustainable innovation.
This innovative work by Su Yang Choi not only pushes the boundaries of sustainable design but also serves as a testament to the enduring power of integrating traditional wisdom with contemporary aesthetics. "Slow2" inspires us to consider how natural materials can be transformed into artistic and functional elements, fostering a deeper appreciation for eco-conscious creativity and mindful design that harmonizes with our environment. It encourages a forward-thinking approach, where the beauty of design aligns seamlessly with ecological responsibility.
