A swarm of gigantic, glowing sea urchins recently appeared on Singapore’s waterfront for the iLight Marina Bay Festival. Choi+Shine Architects constructed the larger-than-life creatures as “lacy rooms” that invite visitors to walk inside and enjoy their intricate structure and visual effects.

The structures are inspired by sea urchin shells, which are elnclosed yet lightweight and porous. The architects recreated the intricate patterns of urchins using white double-braided polyester chord woven in 20 segments and attached to a metal frame. It took 50 people to assemble the structures by hand over a period of two months.

Each sea urchin measures 56 feet in size and weighs around 220 pounds. The lacy pavilions are illuminated by white spot lights, creating the illusion that they glow in the dark. The calming effect and simplicity of the installation visually contrasts Singapore’s skyscrapers and celebrates the city’s cultural diversity.
