Created by architect Li Hao and artist Zhu Jianfei, Uncertain Memory is an ephemeral architecture that was put on display in B.I.G. Carnival (Banana IP Galaxy Carnival).It was set up on the former grounds of Expo 2010—the Shanghai Expo Park, close to Mercedes-Benz Arena and the River Mall. The park with its vast, open space attracts few visitors since strong wind from Huangpu River, the largest river in Shanghai, frequents the Park. In most days, it simply looks desolate.Because the team only had seven days to get the structure ready, and because it was to be taken apart and shipped to its next stop in a display tour, architects adopted a steel framework that is widely used to hang pipework. To assemble the steelwork, one simply needs to join pre-made structural steel components with screws. And it could be dismantled in no time after the carnival.

During daytime, the polycarbonate sheets that formed the surface stressed their presence by throwing back dazzling sunlight, alluring visitors to look no further than on the walls. The sheets became something to be looked at rather than looked through. The filaments used inside, measuring over 12 km in total, would waver in the wind and shimmered in the sun with four evolving colors. Having been properly spaced, they appeared to constitute a translucent curtain that filtered rays of light, stopping one from immediately seeing the inside.The structure’s elevations were made up of two polycarbonate sheets put together, with one rotated by 90-degree. They softened sunlight at different times of the day, adding to a checkered pattern of light and shade. Steel components graced the installation’s inner space with completely straight lines. Two more layers of twin sheets were erected inside the installation, away from the external walls. These inner layers and the walls formed a two-tiered mechanism that lost the uniform clearness of polycarbonate sheet, but still preserved a shred of the material’s transparent quality.

At night, an interactive light control program written by artist Zhu Jianfei changed the lighting on filaments and allowed them to appear in various colors as people walked through this ephemeral architecture. These changes, though subtle, created a rich visual and physical experience. Within the structure, lamplight reflected by the two-tiered system over and over staged a surreal drama of color. The sheets captured light and activities from inside and out, hinting yet blurring the relation of images. The inner space was partially unveiled, the same way elusive, dream-like stories would be staged in a Chinese leather-silhouette device—a sculpture of capricious light then rose up on the site.

The soft filaments delineated a clear and only path one could proceed through the seemingly spatial installation. Having been reflected and filtered by the threads and polycarbonate sheets, light from within the structure could be seen going through complicated changes by people outside. Colors were subtly distorted and the truth was always kept from any observer.

Now that the use of digital technology and elaborate processes are increasing the norm in construction, even large scale urban buildings are often constructed by directly copying a standard approach. However, once it becomes commonplace, any poetic form of technology may gradually lose its ability to construct any meaning. With Indefinite Memory, the architects hope to, by employing some of the basic building tools and materials, challenge the ubiquitous, excessive reliance on technology.

Over 60,000 people visited Uncertain Memory while it was on display, making it one of the most interesting places to take a photo.
